A semi-classical and a semi-empirical methods are employed to obtain line-broadening coefficients for the ν6 band of CH3I-N2 at room temperature (296 K). Calculations are performed for lines in the R, P and Q branches in a broad range of rotational quantum numbers (0J70, K20) typically required for spectroscopic databases. The results demonstrate a good consistency with available Voigt-profile measurements. Owing to the negligible vibrational dependence, our data for the ν6 fundamental can be used for other parallel and perpendicular bands.

室温CH32个 扩宽系数 ν6 基本的

采用半经典和半经验方法来获得线的扩宽系数。 ν6 CH带32个在室温下(296 K)。在宽旋转量子数范围内,针对R,P和Q分支中的线进行计算(0Ĵ70 ķ20),通常是光谱数据库所必需的。结果表明与可用的Voigt轮廓测量具有良好的一致性。由于振动相关性可忽略不计,因此我们的数据ν6 基波可以用于其他平行和垂直频带。
