Spectroscopic Binary This animation shows how the orbits of two stars in a binary system produces a periodic splitting in a spectral line due to the doppler effect.
Spectroscopic Binary Star Download the orginal video from www.astronomy.ohio-state.edu This movie simulates a double-lined spectroscopic binary star system consisting of an F0v primary and M0v secondary in a circular orbit about each other. The orbital plane is oriented along the line of sight in this simulation. The top half of the frame shows the appearance of the two stars seen from above, with the red dot marking the center of mass of the system, and the green dot at left indicating the location of the distant observer. The bottom half of the frame shows the spectrum seen by the distant observer. The absorption lines from the primary star are labeled "A", while those from the secondary star are labeled "B". As the two stars orbit each other, they alternately move towards then away from the observer. This results in their absorption-line spectra getting blue-shifted, then red-shifted, respectively. The pattern of Doppler shifts traces out the orbital motions of each star. A thin "stationary" absorption line appearing between the two lines shows the un-shifted location of each line. Notice that the primary star's absorption lines (labeled "A") only shift a small amount, reflecting its smaller orbital velocity, compared to that of the secondary, which moves much faster. This because the lower mass secondary star must be located farther from the center-of-mass of the system than the primary, and so has to trace out a much bigger circle in its orbit in the same time that the primary does, making ...
Process ***ytical Technology from Pfizer UK Research This video discusses Process ***ytical Technology; By making measurements in the way disclosed in the video, reactions may be tracked in real time, with multiple potential benefits including the ability to stop reactions when they reach a specification (rather than waiting to reach an arbitrary time), thus allowing for a good reduction in cycle time.

How to catch sunlight: UV-3600/ Solidspec-3700 spectrometers in photovoltaic applications Shimadzu, one of the world leaders in ***ytical instrumentation presents the world's first UV-VIS-NIR spectrophotometer with three detectors. The SolidSpec-3700DUV enables spectroscopic detection down to 165 nm in the deep UV region and is therefore a new milestone for Shimadzu, one of the market leaders in spectroscopy. The optical system has been designed to attain the highest sensitivity and contains three detectors: a photomultiplier (PMT) is used for the ultraviolet and the visible region while InGaAs- and PbS-detectors are used for the near-infrared region. This enables the SolidSpec- 3700DUV to carry out highly sensitive measurements in the entire wavelength range from 165 up to 3300 nm. Highly sensitive measurements To date, all conventional spectrophotometers have been using photomultiplier detectors for the ultraviolet and visible range and PbS detectors for the near infrared region. Because none of these types of detectors possess a high sensitivity in the wavelength vicinity where the detectors are being switched, it is impossible to carry out highly sensitive measurements in this wavelength region using conventional spectrophotometers. The SolidSpec-3700DUV uses an additional InGaAs detector and is therefore able to achieve highly sensitive measurements in the detector switching area. - Double monochromator for ultra low stray light - Extra large sample compartment in UV-3700 for non destructive measurements - Unlimited functionality for photovoltaic application

Fourier Transform Infrared (FTIR) Spectroscopy This spectroscopic technique uses a Michelson interferometer to create an interferogram. An infrared source with many wavelengths is passed through a sample, which creates interference patterns as different wavelengths are differentially absorbed. The mathematical technique of Fourier transform is used to convert the raw signal into a recognizable absorption spectra, similar to those produced by a UV/VIS spectrometer.

Test of remote spectroscopic sensing system using terahertz waves:NTT group At NTT, research on terahertz wave technology started in 2006 as a contract project for NICT, using optical communication technology, which is one of NTT's core technology. Five years later, in February 2011, NTT have developed remote spectroscopic sensing system using terahertz waves. The system emits terahertz waves towards the site of an emergency, such as a fire scene filled with smoke and flames, where they are again reflected back toward the receiver. The system converts these waves into a spectrum, which is ***yzed. This enables toxic substances, such as dangerous gases, to be detected instantly from a distance. By integrating NTT's terahertz generation technology, AIST's high-sensitivity terahertz detection technology, and Spectrum Technologies' terahertz spectrum database and ***ysis technology, a remote spectroscopic sensing system has finally been achieved.
Single nanotube experiment with tunable Ti:Sapphire laser Trestles Finesse Dmitri Tsyboulski performs single nanotube experiment with tunable Ti:Sapphire laser Trestles Finesse. More details on related research can be found on Professor Bruce Weisman website. Dr. R. Bruce Weisman and his group investigate the spectroscopy and photophysics of fullerenes and carbon nanotubes. All of these are closed nanoscopic structures formed from carbon atoms. Fullerenes, such as C60, C70, and their chemical derivatives, have unusual molecular properties that cause interesting behaviors following the absorption of light. Time-resolved absorption and emission methods are used to study radiationless decay, photochemical reactions, and energy transfer in fullerenes. Another major research topic is single-walled carbon nanotube spectroscopy. Following the discovery in Weisman?s lab of near-infrared nanotube fluorescence, the group has measured and unraveled the absorption and emission spectra of more than 30 semiconducting nanotube species. Follow-up projects include detailed elucidation of nanotube electronic structure, as well as applications in non-invasive biomedical imaging and ***ytical nanotechnology.

MIRTHE Prototype Laser Spectroscopy Platform From Photonics Spectra magazine: A new development in wireless sensor networks for monitoring trace gases and chemicals uses an infrared laser operating at 2 µm and can detect atmospheric carbon dioxide with a sensitivity of 113 parts per billion in an average time of 1 second. Gerard Wysocki, an assistant professor of electrical engineering whose Princeton group developed the sensor in collaboration with MIRTHE (Mid-InfraRed Technologies for Health and the Environment), a National Science Foundation Engineering Research Center based at Princeton, describes the sensor with assistance from postdoctoral scientist Stephen So. They demonstrated the tunable diode laser absorption spectroscopic (TDLAS) CO2 sensor at SPIE Photonics West 2010 in San Francisco. The sensor is also the subject of a news article in the March 2010 issue of Photonics Spectra magazine.

NIST's Steven Choquette on Building a Common Raman Spectroscopic Library Raman spectroscopy is becoming more widely used in a variety of applications, but spectra from different vendors' equipment can look very different, even for the same material. As a result, the technique can be challenging for nonspectroscopists in the field. NIST has been working on ways to adjust for these differences, to improve method validation and transfer. At the USP science meeting in Toronto recently, Steven Choquette, group leader of NIST's bioassay methods group, described progress so far, and the ultimate goal: a community-supported spectral library and database for Raman. This is a raw video of part of that interview with .
