- Abstract
The effect of (I) S1(1 B2 u) ⇝ T1(3 B1 u) and (II) S1 ⇝ T2 (3 B3 g) ⇝ T1 transitions in naphthalene on the rate constant K of the S1 ⇝ T1 nonradiative transitions to all triplet sublevels s = z, y, x of the T1 state has been investigated in the approximation of vibronically induced spin-orbit couplings, taking into account all out-of-plane vibrational modes. The shapes of the vibrational modes that are most active in these transitions are determined. The calculated values KST = (0.33–0.75) × 107 s−1, obtained with allowance for the I and I + II transitions, are consistent with the experimental values ( KST)exp found by different researchers. It is established in all calculation versions that KST > K > k. This relation is in qualitative agreement with the known magnetooptical data.
