✦ Synopsis

The concept of quenching pairs is proposed for a system of randomly distributed centers which can quench one another rhrou& an ener=g cross-relaxation mechanism. The formula for the quenching rate is derived for the ca5e of an ewiton migrating over the centers. Comparison is made %ith experimental data for cross-relaxational quenchmg of the vibrarionally exited molecule CH&CIq. The micro-interaction parameters are estimated to be CDD = 2 X 1O-33 cm6/s and C DA = 3 X 1O-35 cm6/s. -

A simple modification of the standard cross-polarization method designed for quenching the proton T1 rho dependence when studying polarization transfer is presented. It is demonstrated that by using this simple procedure, new and subtle details of cross-polarization dynamics, previously hidden by th
