Line-mixing between rotational Stark components of CH(3)F self-perturbed and perturbed by helium: Experimental results and IOS analysis
Popis výsledku v původním jazyce
Self- and He-broadening coefficients of microwave transitions of CH(3)F have been measured with and without thepresence of an external electric field. This provides values for the J, K -} J + 1, K (K = 0 - J) transitions for J = 1 and J = 3 as well as for the various J, K, M -} J + 1, K, M' (vertical bar M vertical bar = 0 - K, vertical bar M - M'vertical bar = 0, 1) Stark components. The results and those of a previous experimental study for pure CH(3)F, which show significant line-mixing effects, areanalyzed with a model based on the Infinite Order Sudden approximation. It is shown that the latter leads to very satisfactory modeling of observed values even though no parameter was adjusted since previously and independently determined basic cross-sections are used. The quality of the present predictions is comparable with that obtained previously with a semi-classical approach.
