The ground-state infrared spectra of aluminium monodeuteride: the mass-independent molecular parameters of group IIIa hydrides

The infrared spectra of the monodeuteride of aluminium has been measured in the gas phase in its ground electronic state ( 1Σ) using a diode laser spectrometer. These experimental results were combined with those available for AlH from infrared Fourier transform spectra of the ν=2→0 sequence bands i...

Description
Summary:The infrared spectra of the monodeuteride of aluminium has been measured in the gas phase in its ground electronic state ( 1Σ) using a diode laser spectrometer. These experimental results were combined with those available for AlH from infrared Fourier transform spectra of the ν=2→0 sequence bands in order to calculate a set of mass-independent parameters and mass scaling coefficients. A set of Dunham parameters was also determined from the AlD data. The values of the mass scaling coefficients of the hydrides of four group IIIa metals are discussed.
