Abstract

New technique for measurement of the water vapor absorption coefficient for pulse UV radiation is described. This technique allows the useful signal caused by gas absorption to be separated from the signal caused by absorption by walls and windows of the cell. Both the photoacoustic and photoionization signals are observed in the cell by the action of radiation at the wavelength 266 nm upon water vapor and its binary mixtures with the other gases.
