✦ Synopsis

The single crystal spectra of2,5-distyrylpyrazine (DSP) were obtained in the frequency region of demonstrated photochemical activity. Two observed transitions, n-E* and ~-~*, are assigned at 23300 and 25400 cm ~, respectively. The lower energy transition is shown to be responsible for the reported photoreactivity leading to oligomers while the higher energy one leads to formation of a high polymer through an excitonic mechanism.

Semiempirical MNDO and PM3 molecular orbital calculations have been undertaken to study the structures of the ground and excited states of 2,5-distrylpyrazine dye to assess its activity as a laser dye. In the ground and first excited singlet states, the trans-trans structure of C symmetry is the mos
