Abstract
An apparatus for, optical gain spectra measurements is described, which has been used to determine the gain spectra of several halogen substituted derivatives of 9-acetoxy-10(2′-acetoxy)phenylanthracenes. Using the determinedS 1- andT 1-excited state absorption spectra and other spectroscopic data the gain spectrum have been computed. The changes of the determined laser parameters and spectroscopic data of the halogen substituted derivatives are discussed with reference to the intramolecular heavy atom effect.
