Vibrational Transition Moment for the v₂ Band of CH₃D from Spectra Between 2100 and 2350 cm⁻¹

Abstract

Absolute intensities of the v₂ band of monodeuterated methane in the range of 2100–2350 cm⁻¹ have been measured at 296.3 K by means of a Fourier Transform spectrometer at 0.006 cm⁻¹ resolution. Together with data obtained earlier at 98.3 K we determined the rotationless transition moment |R|=(9.33×10⁻⁴±3%) Debye and the Herman-Wallis factor C=(0.0136±0.0003). We report the intensity measurements and the recalculated intensity values for both temperatures.
