The rotationally resolved S0→T1 transition of jet-cooled pyrazine has been studied using phosphorescence excitation and multiphoton ionization spectroscopy. A computer simulation that divides the relative transition intensity by 2J+1 successfully reproduces the experimental spectra. The results are interpreted in terms of a possible spin-rotational-orientational selectivity in the singlet-triplet coupling that governs the transition oscillator strength.
