Molecular structures of the two tautomers of a β€-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
