Methane absorption bands
WebIn the Near-Infrared (NIR) wavelength region, methane has two vibrational absorption bands: the ”2+2”3combination band, centered at 1.33„m, and the 2”3overtone band, at 1.66„m [12]. Previously, methane has been detected in these bands using conventional cells [1, 13] and HC-PBFs [7, 8]. WebMethane is a trace gas that absorbs heat about 200 times more efficiently than carbon dioxide and has a relatively short lifetime of 12 years. Other trace gases contain fluorine atoms, such as hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs), and perfluorocarbons. Is methane Raman active?
