Abstract

T//1 was measured at 4 MHz and 78 K less than T less than 120 K in mixtures having a Kr molar fraction c up to 0. 8. The transition temperature T//s, corresponding to the solidus curve, was determined for several values of c by observing the large discontinuity in T//1, as in pure CH//4. In the solid phase, the intermolecular dipolar contribution to the relaxation rate is found to be dominant at T greater than 80 K, and the data are in agreement with a simple model based on the Torrey-Sholl theory. Above the melting point, T//1 becomes independent of c, thus suggesting that relaxation may be driven by intramolecular interactions in the liquid phase.
