Vibrational analysis of some pyrazole derivatives

Abstract

The compounds 1,3,5-triphenyl-4,5-dihydro pyrazole, 1,3-diphenyl-5(p-methoxy phenyl)-4,5-dihydro pyrazole and 1,3-diphenyl-5(p-methyl phenyl)-4,5-dihydro pyrazole were prepared. The FTIR and laser Raman spectra of the compounds are recorded and all the normal modes of vibrations are assigned.
