The transverse relaxation times (T2) and total magnetisation of the water protons (h()) were examined as a function of temperature in the range +1.5 C to -54 C. The following results were obtained: (1) The dependence of both T2 and h() upon temperature exhibits hysteresis; (2) T2 decreases with decreasing temperature, with a characteristic activation energy of about 9.2 kcal per mole; and (3) The fraction of "non-frozen" water remaining in a sample below its nucleation temperature decreases with decreasing temperature from 19.4% at -1.2 C to 13.5% at -47 C.54 ppengCopyright is held by the author, unless otherwise indicated.
