Infrared Absorption by Dissolved Gases

Diatomic molecules containing only one element (H2, O2, N2, etc.) do not absorb infrared radiation in the free gaseous state. It has been 

Dissolved carbon dioxide also causes an infrared absorption band in glasses. A narrow absorption band due to dissolved CO2 molecules is found at 4.26//m in sodium aluminosilicate and heavy metal fluoride glasses. Bands due to carbonate species formed by reaction of carbon dioxide with oxide melts have also been reported.
