Popis:	Evidence is presented which indicates that the vibrational predissociation of pyrimidine clusters leads primarily to the production of rotationally very hot S 1 pyrimidines in their zero-point vibrational levels. The generation of vibrationless S 1 pyrimidine is an indication of statistical energy partioning, and it contrasts the pattern of energy partitioning observed in the vibrational predissociation of tetrazine-argon van der Waals complexes. The tendency of the pyrimidine clusters to follow statistical-like energy partitioning is attributed to the greater numbers and reduced frequencies of van der Waals modes of the clusters relative to those of the complex.
