摘要: The energy and oscillator strength of exciton transitions with wave vector k perpendicular to the b crystal axis anthracene are calculated using second quantized boson theory compared results reflection spectroscopy. lattice sums intermolecular interactions used in calculations have a dipole component, computed Ewald's method, nondipolar higher multipole part. latter was obtained by rescaling Silbey, Rice, Jortner who Pariser wavefunctions. spectra faces (001) (201) Clark. Inclusion interaction leads substantial improvement agreement experiment. Predictions made for vectors directions parallel long (L) molecule as well another direction intermediate between normals planes.
