A least-squares fit is presented of 1105 far-infrared and 2860 microwave transitions in acetaldehyde, which sample rotational levels in all torsional states below the lowest-frequency small-amplitude vibration n 10 . Four-fifths of these transitions, involving torsional states below the barrier (Β£ t

We have fit to within experimental accuracy a data set for acetaldehyde obtained by combining \(1014 v_{t}=0.840 v_{t}=1\), and \(430 v_{t}=2\) microwave lines with \(420 v_{t}=1 \leftarrow 0\) and \(404 v_{t}=2 \leftarrow\) 1 far-infrared lines. The principal additions to the previously treated \(v

Methanol data for \(v_{\mathrm{t}}=0\) (below the barrier) and \(v_{\mathrm{t}}=1\) (straddling the barrier) have been treated, using a program based on the formalism of Herbst et al. (J. Mol. Spectrosc. 108, 42-57, 1984). Altogether, 909 microwave lines (mostly assigned a \(50 \mathrm{kHz}\) measur

A global treatment of reported microwave, millimeter-wave, and Fourier-transform far-infrared (FIR) spectra of the C-13 isotopic species of methanol has been carried out for the first two torsional states ( n t Γ… 0 below the barrier and n t Γ… 1 straddling the barrier) of the ground vibrational state
