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
