Abstract

The effects of chemical exchange during rf pulses on deuterium quadrupole echo spectra have been evaluated numerically for single pulses as well as for Levitt-Suter-Emst composite pulses. In principle, the inclusion of exchange effects during pulses of finite length requires lengthy calculations of the evolution of the full density matrix. Fortunately, exchanging lineshapes can be simulated accurately using only the smaller single-quantum transition subset of spin-density-matrix elements provided that the lengths of the pulse-echo intervals are properly adjusted.
