Microwave absorption in the atmosphere by water vapor dimers

Broadening and shifting of the 321-, 325- and 380-GHz lines of water vapor by pressure of atmospheric gases

“…The line pressurebroadening parameters and their temperature dependence were previously studied experimentally [6][7][8][9][10] and theoretically [5, 6,[11][12][13][14][15]. However, except for the self-pressure shifting parameter measured in [6], no experimental data on atmospheric gases pressure-induced shifts are available for this line.…”
