✦ Synopsis
The electric field effect of spectral holes, in the S, +So absorption band of octaethylporphyrin (OEP), is studied in matrices with different dielectric constants, t. The analysis of the hole-contours shows that the Stark effect is linear and provides an average matrix-induced dipole moment, A&,,, which results from the polarization of the OEP molecules by the surrounding host molecules. The values of A&, increase with t of the host. The matrix materials were poly(methylmetacrylate), poly(vinylbutyral), polystyrene and polyethylene.
