测定了[n-CnH2n+1NH3]2ZnCl(n=7~12, 16)配合物在碳氢伸缩、碳氢弯曲、碳碳伸缩和低频区的Raman光谱。发现它们的频率和相对强度与分子中烷基链的链长有关, 并且表现出碳原子数的奇偶效应。从不同的分子堆积结构和分子间相互作用的角度讨论了光谱变化。

The C-H stretching, C-H bending, C-C stretching and the low-frequency vibration regions were investigated by Raman spectroscopy for [n-CnH2n+1NH3]2ZnCl4 with n = 7 ~ 12, 16. Their frequency and relative intensities are related to the length of carbon chain in the mols. and present the odd-even effect to carbon atom nos. in chain. Some changes in spectra are interpreted in terms of the different mol. packing and interaction of chain.

Key words: MOLECULAR STRUCTURE, RAMAN SPECTROMETRY
