Collisional broadening and shifting of the 2_(11)-2_(02) transition of H_2~(16)O, H_2~(17)O, H_2~(18)O by atmosphere gases

摘要

Broadening and shifting of the 2_(11)-2_(02) transition of H_2~(16)O, H_2~(17)O, H_2~(18)O by pressure of water, nitrogen and oxygen were precisely measured at room temperature using spectrometer with radio-acoustic detection of absorption. Shift parameters for all studied lines as well as broadening parameters of H217O, H218O lines were measured for the first time. Comparison of obtained results with previously known experimental and theoretical data is presented.
