The infrared spectra of the enol forms of acetylacetone, hexafluoroacetylacetone, and their deutero analogs have been measured from 4000 to 70 cm−1. Normal‐coordinate analyses have been carried out to estimate the force constants as well as to make theoretical band assignments. The bands at ∼2750, 1460, 945, and 230 cm−1 of nondeuterated acetylacetone have been assigned to the vibrations originating in the O–H···O system. The corresponding force constants are: O–H stretching, 4.00; O–H···O in… Expand
