摘要
测定了[n-C_nH_(2n+1)NH_3]ZnCl_4(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 have been investigated by Hainan spectroscopy for [n-C_nH_(2n+1)NH_3]_2 Z_nCl_4 with n=7~12, 16. It is found that their frequency and relative intensities are related to the length of carbon chain in the molecules and present the odd-even effect to carbon atom numbers in chain. Some changes in spectra are interpreied in terms of the different molecular packing and interaction of chain.
