【Abstract】 Small absorption coefficient of fifteen organic solvents and water were measured at 514. 5nm by means of oppositely crossed laser thermal lens spectrometry using argon ion laser as pump source. Higher sensitivity was obtained. Basic experimental parameters were investigated. The optical system and some measured absorption coefficient of organic solvents were discussed and compared with reference documents.更多还原
