Abstract
This paper reports the investigation of laser-induced optogalvanic effects and spectra of six samples CH3Cl, CH3OH, C2H3OH, C2H3C1, C2H4 and NH3. Intense optogalvanic effects have been observed. The actions of the V-I characteristics and discharge relaxations of discharge tubes on the optagalvanic effects are investigated. The mechanisms of the effects are discussed tentatively. The results show that laser-induced optogalvanic infrared spectroscopy can be used as means of analysis for gases or vapors with high spectral resolution.
