Computationalresults indicate that the no-planar trans-benzanilide is the most stable structure. The spectra indicate that the Franck Condon region photodissociation dynamics have multidimensional character withnine activemodes. The intensity of υ24 mode in methanol is much stronger than that in acetonitrile. Compared with fatty amides and benzamide, phenyl substitution for H atom on-NH2 group makes C=O solvent effects disappear.
结果表明,苯甲酰苯胺的非平面反式结构为最稳定结构;在Frank-Condon区域内,苯甲酰苯胺主要由9个活性振动模组成;其中ν24(苯环上C=C不对称伸缩振动和CCH的面内弯曲振动,NH面内弯曲振动)振动模在甲醇溶剂中的强度远远大于其在乙腈的强度;与脂肪酰胺类化合物和苯甲酰胺的研究结果比较发现,苯基取代-NH2上的H原子使得C=O不再具有明显的溶剂效应。
