The program computes the FC integrals of multidimensional, harmonic oscillators mainly based on the recursion formula given in the papers of Doktorov, Malkin, and Man’ko.enAttribution-NonCommercial 3.0 United StatesResearch Subject Categories::NATURAL SCIENCESResearch Subject Categories::NATURAL SCIENCES::Chemistry::Physical chemistry::SpectroscopyFC-FitSoftware
