Band strength and line half-width of the 10[middle dot]4 [mu] CO2 band
(Elsevier, 1967)
Experimental absorption data using a 10[middle dot]4 [mu] CO2 laser have been re-analysed. The band intensity of the 10[middle dot]4 [mu] (1000-0001) CO2 band is 0[middle dot]0184 cm-1 (atm cm273[deg]K)-1+/-5% at 300[deg]K ...
Electric field induced vibration rotation spectrum of H2 and D2
(Elsevier, 1959)
Electric field induced absorption has been observed for some 8 vibration-rotation transitions of H2 and for 7 of D2. An alternating electric field was used to modulate the transmitted intensity. Percentage absorptions as ...
Tunable laser study of the [nu]10 + [nu]11 band of cyclopropane
(Elsevier, 1980-06)
Diode laser measurements of the [nu]10 + [nu]11 (ltot = +/-2) perpendicular band of cyclopropane have led to the assignments of roughly 600 lines in the 1880-1920-cm-1 region. Most of the spectra were recorded and stored ...
Vibrational analysis of peptides, polypeptides and proteins. XII—fermi resonance analysis of the unperturbed ND stretching fundamental in polypeptides
(John Wiley & Sons, Ltd., 1982-04)
We have obtained the spectrum of β‐poly(L‐alanine‐ND), and find three bands in the ND stretching region. By comparison with Fermi resonance analyses of deuterated derivatives of polyglycine I as well as with α‐poly(L‐alanine‐ND), ...
Inversion-vibration and inversion-rotation interactions in the ammonia molecule
(Elsevier, 1962)
An attempt has been made to extend the theory of ammonia inversion in order to account for the dependence of the inversion splitting on the full set of vibrational and rotational quantum numbers. The potential energy of ...
Inverse Raman spectroscopy of bilirubin and its ditauride
(John Wiley & Sons, Ltd., 1984-08)
The inverse Raman spectrum of bilirubin and bilirubin ditauride were measured under pre‐resonant conditions. Spectra in chloroform and dimethyl sulfoxide were assigned by comparison with model compounds and on the basis ...
Electric Dipole Moments of Rare Gas-Carbonyl Sulfide van der Waals Complexes
(Elsevier, 1993-08)
The [mu]a and [mu]b electric dipole moment components of the Ne-OCS, Ar-OCS, and Kr-OCS van der Waals complexes were determined using Fourier transform microwave spectroscopy. The accuracy of these results was evaluated ...
Centrifugal Distortions in Linear Triatomic Molecules: Application of an ab Initio Approach to HCP
(Elsevier, 1993-12)
Our previously outlined method (J. Mol. Struct. THEOCHEM99, 265-270, 1989) for employing analytic quantum chemical gradients to calculate the geometries, energies, and quartic spectroscopic constants for centrifugally ...
Vibrational analyses of 2,4-dichloropentane and 2,4,6-trichloroheptane
(Elsevier, 1974-04)
This study of the vibrational spectra of 2,4-dichloropentane and 2,4,6-trichloroheptane uses normal coordinate calculations as a probe for the presence of different molecular conformers. The calculations use a complete ...
Analysis of the low temperature fluorescence and phosphorescence spectra of p-difluorobenzene
(Elsevier, 1983-11)
The low temperature fluorescence spectra (4.2 K) of solid solutions of p-difluorobenzene-h4 (pDFB-h4) and -d4 have been recorded and analyzed. The absence of fluorescence from vibrationally excited states at 4.2 K eliminates ...
