Exciton States and Optical Spectra in Linear Molecular Crystals

摘要: Configuration interaction of many Frenkel exciton bands and charge‐transfer states is carried out exactly. Based on the exact solution problem, optical spectra discussed. If monomolecular transition allowed, intensities are borrowed from excitons. Within intensity approximation, resonance peaks antiresonance dips in continuum band expected to appear depending magnitude parameters. Although locations resonances independent orientation light polarization vector, positions numbers antiresonances do depend it. Total number at most one less than bands. In absence depends very strongly nearest‐neighbor charge pair energy with larger for smaller energy. For discrete spectra, mainly distributed equal or more The relative these lines vector. position extra line varies
