N2 - It is shown that nonresonant vibrational energy transfer between molecules in solids can be greatly enhanced by participation of the rotational mode. This mechanism is predicted to dominate over multiphonon-assisted energy transfer for systems with a large mismatch (≫102 cm-1 between the vibrational energy spacings of the donor and the acceptor. Calculations based on this mechanism on the processes NH,ND(3Π,υ = 1) → 12CO, 13CO (in solid Ar) yield results in excellent agreement with the experimental isotope effects.
