The IR absorption intensities of CO stretching bands of pregn-4-ene-3,2O-dione derivatives have been determined. The individual intensities of overlapping bands were calculated by fitting Gauss-Cauchy sum or product functions to the measured spectrum, and numerically integrating the band components obtained. The CO stretching intensity of the 2O-oxo group was found to change considerably upon acylation in position 17 or 21, and characteristically different intensities were obtained for the CO stretching bands of primary, secondary and tertiary acetoxy groups. The results can be utilized in structure elucidation.
