Notes:
The laser Raman phonon spectroscopic technique has been used to study the photopolymerization reaction of 1,4 bis[β-pyridyl(2)vinyl] benzene (P2VB). Raman and infrared spectroscopy have been used to study the intramolecular vibrations of the reactant and the product and to characterize them. Absence of any large Stokes' shift between absorption and emission bands of the monomer crystal shows that exciton-phonon coupling is weak, and the reaction is not likely to be phonon mediated. Phonon spectroscopy shows that the reaction proceeds by a heterogeneous mechanism. Sharp phonon bands of the product, however, suggests that the photopoly P2VB lattice is highly ordered.
