S. Szymanski et al., A CONSISTENT TREATMENT OF COHERENT AND INCOHERENT NUCLEAR-EXCHANGE INA CD3 GROUP, Physica. B, Condensed matter, 226(1-3), 1996, pp. 161-163
Variations with temperature of H-1 NMR single-crystal spectra of a CD3
group undergoing coherent tunneling and incoherent reorientation are
reproduced numerically using a two-parameter NMR lineshape equation in
volving spin variables only.
