The 1H- and 2H-1,2,3-triazoles are isomeric five-membered ring, aromatic heterocycles that may undergo chemical equilibration by virtue of intramolecular hydrogen migration (tautomerization). Using millimeter-wave spectroscopy in the 130-375 GHz freq

Publikováno v: The Journal of Physical Chemistry A. 125:7976-7987
A semi-experimental equilibrium structure (reSE) of pyridazine (o-C4H4N2) has been determined using the rotational spectra of 18 isotopologues. Spectroscopic constants of four isotopologues are reported for the first time (measured from 235 to 360 GH

Publikováno v: Journal of the American Chemical Society. 143:9551-9564
Three cyanobutadiene isomers have been synthesized and their rotational spectra analyzed in the 130-375 GHz frequency range. These species, which are close analogues of known interstellar molecules and are isomers of the heterocyclic aromatic molecul

Synthesis, Purification, and Rotational Spectroscopy of 1-Cyanocyclobutene (C
Autor: Houston H, Smith, Samuel M, Kougias, Brian J, Esselman, R Claude, Woods, Robert J, McMahon
Publikováno v: The journal of physical chemistry. A. 126(12)
The rotational spectrum of 1-cyanocyclobutene from 130 to 360 GHz has been observed, assigned, and least-squares fit for the ground state and the two lowest-energy vibrationally excited states. Synthesis by UV photochemical dimerization of acrylonitr

Vibrationally excited states of 1H- and 2H-1,2,3-triazole isotopologues analyzed by millimeter-wave and high-resolution infrared spectroscopy with approximate state-specific quartic distortion constants
Autor: Maria A. Zdanovskaia, Peter R. Franke, Brian J. Esselman, Brant E. Billinghurst, Jianbao Zhao, John F. Stanton, R. Claude Woods, Robert J. McMahon
Publikováno v: The Journal of Chemical Physics. 158:044301
In this work, we present the spectral analysis of 1 H- and 2 H-1,2,3-triazole vibrationally excited states alongside provisional and practical computational predictions of the excited-state quartic centrifugal distortion constants. The low-energy fun
