摘要:

本文研究了具有C_{3v} -对称性的分子中E-型自旋-转动相互作用对E-型和A_1-型自旋修正之间转换的对称化贡献。利用这些自旋修改之间的意外旋转共振的碰撞增宽的高J下降,有可能协调转换的理论描述与(更新)的实验数据为两个碳取代的氟甲烷同位素。结果得到了两个E型自旋转动常数。它们大约是(氘)甲烷相应常数的1.5倍。

英文摘要:

The symmetrized contribution of E-type spin-rotation interaction to conversion between spin modifications of E- and A_1-types in molecules with C_{3v}-symmetry is considered. Using the high-J descending of collisional broadening for accidental rotational resonances between these spin modifications, it was possible to co-ordinate the theoretical description of the conversion with (updated) experimental data for two carbon-substituted isotopes of fluoromethane. As a result, both E-type spin-rotation constants are obtained. They are roughly one and a half times more than the corresponding constants for (deutero)methane.
