The distortion of the pyrazine molecule in its triplet excited state, as revealed by the appearance of the group theoretically forbidden bands in the sublevel phosphorescence, is analyzed in terms of the polarization of the originally forbidden bands in the sublevel phosphorescence. The experimental results together with some theoretical estimates lead to the conclusion that the pyrazine triplet state is distorted toC2hlsqb;C2(y)rsqb; due to the pseudo Jahnndash;Teller type vibronic coupling involvingb2g(ngr;4) vibrational mode.
