Notes:
This paper considers the origin of the excited states and spectroscopic features of polar molecular compounds of N,N-dimethylaminobenzylidene 1,3-indandione (DMABI). Evidence of a strong exciton-phonon interaction and its effects on the exciton absorption and luminescence spectra was discovered. The spectral features were related to the crystal structure and were ascribed to self-trapped charge transfer excitons. A weak, narrow luminescence line was also observed in resonance with the lowest absorption band and was attributed to free exciton radiative recombination.
