Best-parameter search in asymmetric rotor models

The Davydov model is analysed by performing a least-squares fit to the experimental energy levels while varying the parameters simultaneously until an optimum adjustment is obtained. Special emphasis is put on the feasibility of the method proposed to explain the higher vibrational states. The best...
