摘要

研究了Au2I2(CH3)4在90 ~ 298°K温度下的非对称CH3变形振动的红外光谱带形。在Bulanin和Orlova以及Rakov的基础上，用两种方法计算了固态内旋势垒。该屏障的平均值估计为270±70厘米。

Barriers to internal rotation of CH3 groups in solid Au2I2(CH3)4 from infra-red band shape measurements

The band shape of the asymmetric CH₃ deformation vibration in the infra-red spectrum of Au₂I₂(CH₃)₄ has been studied as a Cs I disk at temperatures from 90°K to 298°K. The barrier to internal rotation in the solid state has been calculated by two methods based on those of Bulanin and Orlova, and of Rakov. A mean value of the barrier is estimated as 270 ± 70 cm.⁻¹.
