IPPP — A program for the RPA calculation of transmission mechanisms of spin-spin coupling constants

Title of program: IPPP Catalogue Id: AAFL_v1_0 Nature of problem The IPPP program calculates NMR spin-spin coupling constants in molecular systems, based on a standard INDO computation, within the RPA (or CHF) approximation solved by the polarization propagator technique. The transmission mechanisms are analyzed by the inner projection of the propagator matrix.
