PROTON MAGNETIC RESONANCE ABSORPTION IN ANHYDROUS POTASSIUM STEARATE

Abstract
The proton magnetic resonance absorption in anhydrous potassium stearate has been measured over the temperature range −190 °C to 182 °C. Abrupt changes in line width have been found between 55 °C and 62 °C, and between 170 °C and 171 °C; these changes correspond approximately to known phase transitions. The reduction in line width and second moment with rising temperature is discussed.
