摘要：
The H216O vapor absorption line broadening by nitrogen pressure is investigated in the range of 12411–12421 cm−1using a laser optoacoustic spectrometer with a Ti: sapphire laser having a lasing line width of 50 kHz. The broadening coefficients of 7 H2O lines determined by transitions to levels with the vibrational quantum numbers v = 4–8 are measured with an absorption sensitivity threshold of 10−8cm−1. Experimental line half-widths are compared with their values calculated by the semi-empirical method.
