Multiple fluorescence emission bands are observed for unsymmetrical squaraines, a class of unsymmetrical donor-acceptordonor molecules, in organic solvents at room temperature and are shown to be vibrational tine structures of the emissions of the excited states of the unsymmetrical squaraine and it
The benzimidazole moiety is present in a great variety of pharmaceutical compounds with anthelmintic action and other applications. These compounds exhibit native fluorescence which often depends on the substituents on the benzimidazole ring and the solvents. The fluorescence emission also changes w
The pulse-height distributions for 241Am and 131mXe in PPO solutions of the aromatic hydrocarbons, i.e. benzene, o-xylene, m-xylene, ethylbenzene and cumene are found to shift toward higher pulse-heights with decreasing temperature. Under u.v. excitation, the fluorescence intensity of these pure aro
