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&,,, w
Oprical hole-burning experiments at 2 K with chlorin in polymethylmerhacryiare (PhIMA), polystyrene (PST) and polyvinyibutanal (PVB) gave hole widths of 1.2, 1.6 and 0.75 GIlz. Prclitninar\_v temperaturedependent measurements in PVB susest that the linewidth xt 0 K approsimates the lifetime-limited
