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.
