L. Nemes, A. R. W. McKellar, and J. W. C. Johns, "Laser-Stark and Fourier-transform spectroscopy of the ν3 band of monodeuterated formic acid, HCOOD," J. Opt. Soc. Am. B 4, 1165-1172 (1987)
The ν3 fundamental band of monodeuterated formic acid, HCOOD, at 5.64 μm has been studied by using a combination of CO-laser-Stark spectroscopy and high-resolution Fourier-transform spectroscopy. The analysis of the Fourier-transform data, together with all previous pure rotational ground-state data, gave precise values for the ν3-band origin and rotational and centrifugal distortion parameters. Slightly refined ground-state parameters were also obtained. A c-type Coriolis interaction between ν3 and ν6 + ν7 was included in the analysis, resulting in a value for the interaction parameter and for some effective parameters of the perturbing state. A second weaker Coriolis interaction between ν3 and ν5 + ν9 was noted but not analyzed. The Stark data yielded precise values for the μa and μb dipole-moment components in the ground and excited states.

Line quality is indicated by the number in the column marked Q. Weights in the fit were chosen as follows: Q= 1, W = 1; Q = 2, W = 0.25;Q = 3, W = 0.01; Q = 4, W = 0.0025;Q = 5, W = 0 (see text). The observed minus calculated wave numbers are given in the column marked R in units of 10−4 cm−1.
Based on a fit to the present FT data (Table 1) and the known microwave transitions of HCOOD (Ref. 9). Uncertainties in parentheses are one standard error from the least-squares analysis.
These values were held fixed in the fit.
For the interaction between ν3 and ν6 + ν7, with the latter state represented by p. Centrifugal distortion parameters for state p were held fixed at their ground-state values.

Line quality is indicated by the number in the column marked Q. Weights in the fit were chosen as follows: Q= 1, W = 1; Q = 2, W = 0.25;Q = 3, W = 0.01; Q = 4, W = 0.0025;Q = 5, W = 0 (see text). The observed minus calculated wave numbers are given in the column marked R in units of 10−4 cm−1.
Based on a fit to the present FT data (Table 1) and the known microwave transitions of HCOOD (Ref. 9). Uncertainties in parentheses are one standard error from the least-squares analysis.
These values were held fixed in the fit.
For the interaction between ν3 and ν6 + ν7, with the latter state represented by p. Centrifugal distortion parameters for state p were held fixed at their ground-state values.
