Abstract:

Calculated self- and nitrogen-broadening coefficients of methylcyanide lines are presented. The calculations are performed at the room temperature (Т = 296 K) for ~ 1 400 lines, rotational quantum numbers vary in ranges 0 ≤ J ≤ 70; 0 ≤ K ≤10. The temperature exponents for every value of broadening in the case of the Earth and Titan atmospheres temperature ranges are calculated. The calculations are made by a semi-empirical method, which is a modification of impact theory, based on the use of measured values of line contour parameters. A good agreement is obtained with experimental data.

Keywords:

line-broadening, symmetric top, methylcyanide, line-contour, intermolecular interactions
