Wide line nuclear magnetic resonance study of molecular motions in solid sulpholan
Abstract
Sulpholan has been studied by the wide line n.m.r. method over the temperature range 77 to 310 K. Two transitions were observed. The transition centred at 210 K is probably due to molecular reorientation about the two-fold axis, and the transition at 288 K is due to both isotropic rotation and self diffusion. The higher temperature transition shows a hysteresis effect.
