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.
Explain why water is pale, greenish-blue. Water is transparent to nearly all visible frequencies of light. Water molecules absorb infrared waves because they resonate to the frequency of infrared waves. The energy of infrared waves is transformed in to kinetic energy of the water molecules. Infrared is a strong component of the sunlight that warms water.
