54. Approximate Selection Rules for | K | = 1-0 and 1-1 Tunneling-Rotation Transitions in the Methanol Dimer
Published: 9/1/2000
Authors: N Ohashi, Jon Torger Hougen
Abstract: Approximate K = 0 and |K| = 1 tunneling-rotation eigenfunctions for the four A, four E, and one G symmetry species present in the methanol dimer, derived from molecular parameters obtained previously from a least squares fit to transition frequencies ...

55. K-Scrambling in a Near-Symmetric Top Molecule Containing an Excited Non-Coaxial Internal Rotor
Published: 6/1/2000
Authors: J Ortigoso, Jon Torger Hougen
Abstract: Classical trajectories on rotational energy surfaces and coherent-state quantum projections have been used to study an asymmetric-top molecule containing a freely rotating internal symmetric top whose symmetry axis is not coincident with a principal ...

56. Contact Transformations and Determinable Parameters in Spectroscopic Fitting Hamiltonians
Published: 2/1/2000
Authors: M A Mekhtiev, Jon Torger Hougen
Abstract: In recent least-squares fits of torsion-rotation spectra of acetaldehyde and methanol it was found possible to adjust more fourth-order parameters than would be expected from traditional contact-transformation considerations. To investigate this dis ...

Published: 6/1/1999
Authors: J Ortigoso, I Kleiner, Jon Torger Hougen
Abstract: The problem of attaching torsional and rotational quantum number labels to computer-generated-numerical eigenvectors with extensive basis set mixing is considered for the internal-rotation-overall-rotation problem in molecules with one methyl top. Q ...
