The spin flip-flop transition rate is calculated for the case of spectral spin diffusion within a system of dipolarly coupled spins in a solid where the lattice vibrations are present. Longwavelength acoustic phonons time-modulate the interspin distance r ij and enhance the transition rate via the c
