Vibrational assignment and absolute integrated intensities of liquid bromobenzene-d5 between 4000 and 400 cm−1 at 25 °C

This paper continues the analysis of the integrated intensities of substituted benzenes. In particular, the absolute integrated vibrational intensities of bromobenzene-d5 are presented. The previously reported imaginary molar polarizability spectrum of bromobenzene-d5 was fitted with 231 CDHO bands. The majority of the bands are assigned to fundamentals, first overtones or binary combinations (sum and difference). From the fitted parameters, the integrated intensities of the fundamentals have been determined. Using the F-Sum rule, the intensities are compared to those of bromobenzene-h5. The intensities agreed very well between the two isotopomers.
