Abstract:
The high resolution absorption spectrum of CH<sub>3</sub>D in the region of 900-1700 cm<sup>-1</sup> has been revisited on the basis of new long path experimental data recorded with the Fourier transform spectrometer at Kitt Peak. A theoretical model used previously for spherical rotors has been adapted for polyatomic molecules in order to analyze the vibrational polyads of CH<sub>3</sub>D simultaneously.
