Infrared studies of acetophenone and its deuterated derivatives

Abstract The i.r. spectra of acetophenone and their deuterated analogues (- d 3 , - d 5 , - d 8 ) in the liquid-phase have been recorded and analyzed in the range 4000-130 cm −1 . Additional data on band contours in the gas-phase, in conjunction with the deuteration effects, allowed us to assign all the fundamentals for the four isotopic varieties. A valence force field calculation was also used to support the proposed assignment.
