摘要：

Theoretical self-broadening coefficients and associated temperature dependences for methyl cyanide lines in parallel (Delta K= 0) bands are reported for large ranges of rotational quantum numbers (0 <= J <= 70, K <= 20) requested by spectroscopic databases. The calculations are performed by a semi-empirical method, particularly suitable for active molecules with large dipole moments, which needs only a few experimental data for model parameters fitting. Since the common power law for the temperature-dependence exponents is invalid for wide temperature ranges, two separate sets of temperature exponents are provided for Earth and Titan atmospheres applications.
