The spectral behavior of pyrazoline derivative 1-phenyl-3-(4-N,N-dimethylaminostyryl)-5-(4-N.N-dimethylaminophenyl)-2-pyrazoline in various solvents have been studied. According to the results obtained the general effects and the specific effects of interaction between the molecule of this derivative and the solvents used were investigated. It was found that the fluorescence quenching of pyrazoline solution by different species can be used as a method for studying both general and specific interaction between pyrazoline derivative and molecule of solvents.

Key words: Pyrazoline derivative, Solute/Solvent interaction, Fluorescence quenching
