Ir spectrograph
WebCalifornia Institute of Technology The Infrared Spectrograph (IRS) This plot shows data captured by Spitzer's IRS instrument, indicating a strong signature of water vapor in the disk of gas and dust surrounding a young star. The Infrared Spectrograph was one of Spitzer's three science instruments. WebSpitzer carries three scientific instruments: an IR array camera (IRAC), an IR spectrograph, and a multiband imaging photometer. Fazio is the principal investigator for Spitzer’s IRAC. Only two of the IRAC’s four 256- × 256-pixel detector arrays, working at 3.6- and 4.5-µm wavelengths, remain operational in its warm mission. ...

Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used … See more Infrared spectroscopy exploits the fact that molecules absorb frequencies that are characteristic of their structure. These absorptions occur at resonant frequencies, i.e. the frequency of the absorbed radiation matches … See more IR spectroscopy is often used to identify structures because functional groups give rise to characteristic bands both in terms of intensity and position (frequency). The positions of these … See more Infrared spectroscopy is a simple and reliable technique widely used in both organic and inorganic chemistry, in research and … See more Two-dimensional infrared correlation spectroscopy analysis combines multiple samples of infrared spectra to reveal more complex properties. By extending the spectral information of a perturbed sample, spectral analysis is simplified and resolution is … See more The infrared spectrum of a sample is recorded by passing a beam of infrared light through the sample. When the frequency of the IR is the same as the vibrational frequency of a bond or collection of bonds, absorption occurs.
