✦ Synopsis

Violations of coherence transfer selection rules in multiple quantum NMR spectra of isotropic solutions are reported. In some cases these wolations can be accounted for by strong coupling effects, as demonstrated via computer simulations. In many cases, however, the "forbidden" peaks likely arise due to differential relaxation rates of degenerate smgle quantum transitions of magnetically equivalent nuclei.
