The Normal Coordinate Treatment for Molecules with ,,, ,,, ,,, and ,,, Symmetry,he normal coordinate treatment (NCT) method, which also serves to check the frequency assignments for the model. This method, which illustrates a useful application of group theory, depends on the bond lengths and bond angles of the model. Knowledge of force constants (the restoring force between tw
