| Abstract: | The effect of cross relaxation due to inelastic collisions on the inversion doublets of ammonia in the far infrared was studied by interferometric spectroscopy. Line widths and cross-relaxation rates were measured for several rotational transitions, using CH2 = CF2, C2H6, CF4 and SF6 as perturbing gases in the pressure range from 1 to 17.5 atm. The J-dependence of the observed cross-relaxation rates was calculated using a first Born approximation. |
