The transition probability win two symmetrical double-well potentials (Q'-2 1 Q 1 and Q"-2Q2 ) is found by the path-integral method for tunnelling symmetrically coupled with a g vibration (q 1 QI and gQZ for the above-mentioned potentials, respectively) for arbitrary values of the tunnelling time 7 and vibration frequency 52,. The dependences of w on temperature and particle mass h are found which explain the low values of cross-over temperatures experimentally observed in solid-phase cryochemical reactions (as compared with FI/T) and quite weak decrease of w with the rise ofy, (weaker than -In WT &I').

## Recewed 5 June 1972 A new formula for the rate of photochemical dissociation is presented within the Bixon-Jortner model of radiationless transitions in large organic molecules. The essence of this formula is that if the rate of photochemical decomposition is much larger than the rate of radiat
