The cross-polarization dynamics between 1 H and 19 F in a Viton-type fluoroelastomer were studied using 19 F magic angle spinning (MAS) and 1 H ! 19 F cross-polarization (CP)/MAS NMR at 188.29 MHz. The phenomenological theory of spin thermodynamics based on the spin temperature hypothesis was employ
Rotor-synchronized amplitude-modulated Hartmann-Hahn crosspolarization has been applied under fast magic-angle spinning to a powder sample of ferrocene. The influence on the cross-polarization process of the heteronuclear double quantum (flop-flop) transitions induced by the amplitude modulation for
