... are given by 1/T1 = 1/T2 = c. According to the Stokes- Einstein-Debye relation, the quantity c /T is a constant as a function of temperature when c is the rotational correlation time. This has been found to be a general property of fluids. Only in rare cases, such as in some supercooled colloids, has...
