Abstract
Pyrazine (1,4-diazabenzene) has played a central role in the development of the theory
of radiationless transitions. In this paper, we will describe studies of the decay behavior
and fluorescence quantum yield of the isolated molecule and several of its isotopically
labelled derivatives following pulsed dye laser excitation of “single” rotational levels
of the
