【Abstract】 By the FT-IR spectra, some questions of the structure of four kinds of 1,3- diphenyl-4-acyl-5-phrazolone are discussed. It is indicated， that the influence of the substituents at position 4 of the pyrazoloes on the carbonyl is obvious and that these compounds exist in the form of tautomer.更多还原
