Definition
Measurement method of nuclear magnetic resonance spectroscopy for obtaining high-resolution solid-state nuclear magnetic resonance spectra on nuclei with high gyromagnetic ratio such as \(\ce{^{1}H}\) and \(\ce{^{19}F}\).

Note
CRAMPS is based on coherent-averaging theory, which attempts to describe the time evolution of a system in terms of an average Hamiltonian derived from the density matrix formalism of quantum mechanics.
