WebJan 30, 2024 · Infrared (IR) spectroscopy is one of the most common and widely used spectroscopic techniques. Absorbing groups in the infrared region absorb within a certain wavelength region. The absorption peaks within this region are usually sharper when compared with absorption peaks from the ultraviolet and visible regions. WebThe James Webb Space Telescope, set to launch in 2024, will observe in wavelengths that overlap the ones Spitzer observes. (During its “cold” or cryogenic mission, which ran from 2003 to 2009, Spitzer observed infrared wavelengths from 3 to 160 microns. Webb will observe from 0.6 through 28 microns.) psma pet scan northern california https://jsrhealthsafety.com
