- We calculated methyl chloride self-broadening coefficients using two methods.
- Rotational quantum numbers were J from 0 till 70 and K from 0 till 20.
- The temperature exponents were calculated for every mentioned line.
CH335Cl self-broadening coefficients at various temperatures of atmospheric interest are computed by a semi-empirical method particularly suitable for molecular systems with strong dipole-dipole interactions. In order to probe the dependence on the rotational number K, the model parameters are adjusted on extensive room-temperature measurements for Kâ¤7 and allow reproducing fine features of J-dependences observed for Kâ¤3; for higher K up to 20, the fitting is performed on specially calculated semi-classical values. The temperature exponents for the standard power law are extracted and validated by calculation of low-temperature self-broadening coefficients comparing very favorably with available experimental data. An extensive line-list of self-broadening coefficients at the reference temperature 296 K and associated temperature exponents for 0â¤Jâ¤70, 0â¤Kâ¤20 is provided as Supplementary material for their use in atmospheric applications and spectroscopic databases.
