Molecular structures of the two tautomers of a ␤-diketone 1-phenyl-3-methyl-4-benzoyl-5pyrazolone (PMBP) were studied by MS, UV, IR, and X-ray diffraction methods. The mass spectra show little difference for the two forms of PMBP, while there are notable differences in the IR spectra as KBr pellets

The broad infrared bands of the polymorphic crystals of I-phenyl-3-methyl-4-benzoyl+pyrazolone (PMBP) were assigned unequivocally by examining the IR spectra of solutions and Raman spectra. The strong band at 2550 cm-' of a colourless crystal was attributed to an intermolecular hydrogen bond NH...O=
