PES2MP (Potential Energy Surface Mapping to Multipole Expansion Series)
Multipole expansion
2D and 4D multipole expansion code (using Legendre polynomials and Spherical Harmonics respectively)
for fitting PES into radial coefficients is provided as jupyter-notebook files.
Both codes use least square fit (achieved by taking the pseudo-inverse of Legendre/Spherical-Harmonics coefficients stored in a 2D matrix).
Currently limited to rigid rotor - atom (2D) and rigid rotor - rigid rotor (4D) collision
