The near infrared absorption spectrum of liquid water at 20Â°C has been reinvestigated using a PbS cell detector system. The total spectral range investigated was from 0.70 to 2.50Î¼. A curve is included which shows five prominent absorption bands at 0.76, 0.97, 1.19, 1.45, and 1.94Î¼; and a table gives experimental results of water absorption at 20Â°C.
Infrared Spectroscopy. (also IR spectroscopy), the branch of spectroscopy that includes the production, study, and use of emission, absorption, and reflection spectra in the infrared region of the spectrum.nfrared spectroscopy is used in the study of the structure of semiconductors, polymers, biological entities, and living cells. High-speed spectrometers make it possible to obtain absorption spectra in fractions of a second and are used in the study of rapidly transpiring chemical reactions.
