Calculation of the energy levels of weakly bound molecular trimers: Application to (H-2)(3)

A general method to calculate the ro-vibrational energy levels of molecular clusters is discussed. The approach is a variational method based on orthogonal coordinates with an expansion of the potential-energy surface in coupled spherical harmonics.

Description
Summary:A general method to calculate the ro-vibrational energy levels of molecular clusters is discussed. The approach is a variational method based on orthogonal coordinates with an expansion of the potential-energy surface in coupled spherical harmonics. Initial application of the method to (H2)2 yielded significant results.
