✦ Synopsis

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

Pseudo-Stark splittings have been measured for optical transitions of V\*, Cr3+ and Co3\* in corundum (cr-AlaO3) when these crystals are submitted to dc and ac fields. Quantitative results have been obtained for dc electric field parallel to the C3-axis. With the electric field perpendicular to the
