SIMPSON is a command line program for simulating solid-state NMR spectra given a spin system, pulse sequence, and experimental parameters.

GSim is a free software tool for the visualisation and processing of experimental and simulated nuclear magnetic resonance (NMR) spectra. It can be used to plot output files from SIMPSON into spectra.
