The infrared spectrum of C3O2 : The interaction between [nu]7 and the [nu]2 and [nu]4 vibrations
(Elsevier, 1977-07)
The , , and hot bands of the [nu]4 fundamental of C3O2 in the 1580 cm-1 region were analyzed from tunable diode laser spectra and the ground state to band at 1644 cm-1 from Fourier transform spectra (FTS). The molecular ...
Microwave spectrum and structure of ethylene ozonide-D4
(Elsevier, 1977-04)
Rotational spectra of six isotopic species of ethylene ozonide-D4 have been assigned. The Op---Op distance was calculated six independent ways using Kraitchman's substitution equations, and values between 1.458 and 1.462 ...
Interpretation of the vibrational behavior of methyl and substituted methyl radicals perturbed by alkali halide molecules
(Elsevier, 1970-12)
The observed vibrational behavior of free and alkali halide-perturbed methyl radicals in low temperature inert matrices is rationalized on the basis of the relaxation of the molecular charge distribution of the methyl ...
The emission and absorption spectra of chromyl chloride in an argon matrix at 4 K
(Elsevier, 1974-07)
The emission and absorption spectra of chromyl chloride (and the pure 35Cl isotopic species) have been obtained in an argon matrix at 4 K. In emission, two systems are obtained and these correlate with the two systems ...
A high-resolution study of the OH-stretch fundamental of methanol
(Elsevier, 1975-07)
The OH-stretch fundamental of CH3OH has been observed with 0.025 cm-1 resolution between 3430 and 3940 cm-1 and the resulting spectrum deconvoluted using the procedure of P. A. Jansson. Approximately 600 lines have been ...
Rapid computation of the Voigt profile
(Elsevier, 1976-07)
A computational procedure is described to evaluate the Voigt function with a maximum relative error of about one part in 104, for use in line-by-line transmittance calculations and other applications. An efficient Fortran ...
The microwave spectrum, dipole moment and low frequency vibrational states for phosphabenzene
(Elsevier, 1972-06)
The microwave spectrum of the ground vibrational state and seven lowfrequency vibrational states for phosphabenzene (C5H5P) have been assigned. The small positive inertial defect and the alternation of intensities due to ...
The microwave spectrum, structure and nuclear quadrupole coupling constants for stibabenzene
(Elsevier, 1978-05)
The microwave spectrum of 121-SbC5H5, 123-SbC5H5, [beta]-dideutero 121-SbC5H3D2 and 123-SbC5H3D2 has been assigned in the region 26.5-40.0 GHz. The respective rotational constants and uncertainties are: A = 4512.69 +/- ...
Electronic structure of arsabenzene: Microwave spectrum, dipole moment, and nuclear quadrupole coupling constants
(Elsevier, 1975-09)
The microwave spectrum of arsabenzene was analyzed; a dipole transitions were observed. The following rotational constants were obtained; A = 4871.03 +/- 0.18 MHz, B = 2295.87 +/- 0.01 MHz, C = 1560.10 +/- 0.01 MHz. The ...
Bisquaternary ammonium compounds as potential tumor imaging agents
(Elsevier, 1979)
Reports of rapid accumulation of 3H- or 14C-labelled hexamethonium in cartilaginous tissues after intravenous administration to rats and mice and of binding of hexamethonium to chondroitin sulfate in vitro prompted synthesis ...
