摘要: The first analysis of rapid intramolecular motions triphenyl phosphite by 2H NMR is presented. fragile slowing down the primary relaxation followed a solid-echo method. occurrence fast reorientation phenyl side groups demonstrated in supercooled liquid state, identified as two-fold flip on basis simple lineshape simulations. Coexistence both static and motionally averaged components “two phase” spectra indicate broad distribution correlation times for this relaxation. This dynamical behavior shown to persist glacial phase.
