The new simulator, implemented as a jMRUI plugin, addresses the needs of a practical spectroscopist as well as a pulse sequence physicist. Pulse sequences, optionally controlled by protocols, may include arbitrarily modulated RF and gradient pulses, cycles, overlapping pulses. Homo- or heteronuclear spin systems are described by spatial position, chemical shifts, J-coupling, and the Redfield relaxation matrix, whose parameters can be derived from simplified models (Solomon, component relaxivities of coherences). It can be used for the study of the effects of spectrally or spatially selective excitation, steady-state formation, magnetization transfer, pulse sequence optimization.
