Abstract: Based on previous papers, combining model potential function method with MNDO, MINDO/3 method, this paper suggests a new method of determining force fields for polyatomic molecules.The force constants obtained by this method are applied to calculating the vibrational frequencies of polyatomic molecules, resulting in a satisfactory outcome with a higher accuracy.

Key words: Model potential function method, MNDO, MINDO/3, Force field, Vibrational frequency
