Overview
SIMPSON is a general purpose solid-state NMR simulation software [1]. SIMMOL is an helper software that allow to describe the spin system and calculate all needed parameters. It work by numerical integration of the Liouville-von- Neumann equation, this require a complete description of the Hamiltonian of the system ( this is done by simmol, and contains all coupling, zeeman interaction, pulse ... ) and a starting density matrix.
