Abstract
Vibrational transitions of pyrazine in the lowest triplet state have b een observed as transient changes in the intensity of the phosphoresce nce induced by the free-electron laser FELIX. All seven fundamental in frared-active modes in the range of 250 to 1600 cm(-1) have been detec ted and all vibrational frequencies are found to be considerably lower than the corresponding ones in the ground state.
