Abstract
Temperature dependent spectra of an oxazine laser dye, cresyl fast violet, has been studied within a concentration range of 5.0 × 10−5 M to 8.0 × 10−4 M. The temperature induced shifting of monomer–dimer equilibrium is accompanied by partial unfolding of dimer geometry in solution. While the modified π–π interaction due to temperature variation affects both monomer and the dimer spectra, changes in the geometrical disposition of the dimer are manifested in the exciton splitting of the dimer spectra.
