Dependence of the sign of the pressure shift of molecular lines upon the type of disturbing gas
Abstract
Submillimeter-wave spectroscopy was used to study the shift and broadening of J = 1-0 transitions of the (N-14)H3 molecule and 1(10)-1(01) transitions of the H2(O-18) molecule produced by the pressure of various disturbing gases (NH3, H2O, H2S, and HCl). The sign of the line shift is found to depend upon the type of disturbing gas. The results obtained are explained by a model of the dynamic Stark shift of levels.
