摘要：
The change in electric dipole moment and molecular polarizability of indocarbocyanine (ICC) in Langmuir-Blodgett films upon excitation into S-1 is estimated to be 5.3 x 10(-32) C m (0.016 D) and 3.5 x 10(-40) J(-1) C-2 m(2) (3.1 in units of 4 pi epsilon(0) Angstrom(3) ), respectively, based on the electroabsorption spectra. A directional nonradiative process in S-1 of ICC is also shown to be affected by an external electric field, based on the electrofluorescence spectra combined with the electroabsorption spectra.
