The Raman spectrum of but-3-enyl methyl ether, CH(2)CHCH(2)CH(2)OCH(3) is reported and compared with those of its homologues in which a methyl group is substituted for a hydrogen atom on one of the carbon atoms of the alkenyl chain. Attention is focused on the influence of this methyl group on the bands in the spectrum associated with specific CH, skeletal stretching and bending vibrations. The use
报告了丁3烯基甲基醚CH(2)CHCH(2)CH(2)OCH(3)的拉曼光谱,并将其与其中一个甲基取代了一个氢原子的同系物的拉曼光谱进行了比较链烯基链的碳原子数。注意力集中在该甲基对与特定CH,骨骼伸展和弯曲振动相关的谱带中的影响上。从头算DFT量子力学计算的使用来帮助进行这些分配,揭示了骨骼振动中的高度模式混合。强调了这类模型研究在完善具有分子结构的拉曼光谱中特定谱带存在与不存在之间的相关性的价值。
