Spin relaxation and chemical exchange in NMR simulations

J Magn Reson. 2000 Jan;142(1):11-23. doi: 10.1006/jmre.1999.1812.


Theory for describing the density matrix of a spin system experiencing chemical exchange and relaxation during the steps of an NMR experiment is presented in a form suitable for computation. Features in the theory that arise from exchange are discussed in detail, and comparisons to the exchange-free situation are made. A general computer program to carry out simulations of NMR experiments is described, and several examples of its performance are presented.
