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.
Measurements of the magnitude and spectral distribution of the Raman-scattering coefï¬cients of pure. water ~b. rw! and seawater ~b. rs! are presented. Two independent measurements of the spectral distribu-. tion of the Raman-scattering coefï¬cient of pure water were made for incident wavelengths ranging from. 250 to 500 nm. These measurements revealed a strong dependence of b. rw on wavelength that could be.
