【Abstract】 A normal coordinate analysis was performed for all vibrational modes of three groups,acetate,double bond and straight chain alkane in cis-3-hexehol acetate as a nodel for long chain mono-unsaturated alcohol esters by using local syametry coordinate force fietd.The assignment of the normat frequencies was made.Calculated frequencies were in good agreement with the observed ones.A set of force constants for the vibrational modes and some main interaction force constants were obtained.The double degenerate vibrational aodes in aethyt for stretching,deformation and rooking were differentiated.更多还原
