Normal-mode analysis of infrared and Raman spectra of poly(vinyl fluoride)
(Elsevier, 1992-03-02)
Infrared and Raman spectra of samples of poly(vinyl fluoride) (PVF) have been recorded. The vibrational spectra have been analyzed by means of normal-mode calculations. A force field was derived by using 2-fluorobutane as ...
Carbon suboxide as a quasilinear molecule with a large amplitude bending mode : Determination of the molecular constants and the [nu]7 potential function
(Elsevier, 1976-12)
The model of a quasilinear molecule with a large amplitude bending mode is used to treat C3O2. The Hamiltonian operator, including the rotation-vibration interaction, is derived allowing only a single vibrational degree ...
Vibrational spectra and normal coordinate analysis of CF 3 OF and CF 3 OCl
(John Wiley & Sons, Ltd., 1980-08)
The IR spectra (1400 cm −1 to 160 cm −1 ) of the gases at ambient temperature and the Raman spectra (below 1400 cm −1 ) of the liquids near −196°C are reported for CF 3 OF and CF 3 OCl. All fundamentals are assigned under ...
Rapid computation of the radiative absorption rate in the v3 mode of mesospheric and lower thermospheric ozone
(Elsevier, 1991-11)
We have developed an algorithm to calculate rapidly and accurately the rate (photons-molecule-1-sec-1) at which the ozone v3 fundamental band absorbs i.r. radiation in the terrestrial upper mesosphere and lower thermosphere. ...
The chlorine nuclear quadrupole coupling tensor in chlorotrifluoroethylene
(Elsevier, 1988-12)
The 273 hyperfine components from 56 rotational transitions of chlorotrifluoroethylene were measured with a Fourier transform microwave spectrometer. A global least-squares fit was made to the rotational constants, quartic ...
A band model formulation for very nonuniform paths
(Elsevier, 1972-05)
Anomalous behavior has been observed when molecular band-models incorporating the Curtis-Godson or similar approximations are applied to problems characterized by a large variation in temperature along the optical path. ...
Glycoproteomics in neurodegenerative diseases
(Wiley Subscription Services, Inc., A Wiley Company, 2010-01)
Protein glycosylation regulates protein function and cellular distribution. Additionally, aberrant protein glycosylations have been recognized to play major roles in human disorders, including neurodegenerative diseases. ...
Vibration-rotation interactions in infrared active overtone levels of spherical top molecules; 2[nu]3 and 2[nu]4 of CH4, 2[nu]3 of CD4
(Elsevier, 1962)
The theory of the vibration-rotation lines of the first overtones of the infrared active fundamentals of tetrahedral molecules has been re-examined. Theory predicts an overtone spectrum consisting of five P, Q, and R ...
Microwave spectrum and structure of ethylene ozonide: Effects of large axes rotations in structure calculations
(Elsevier, 1976-03-30)
Rotational spectra for 14 isotopic species of ethylene ozonide have now been assigned. The consistency of the Kraitchman substitution structure was checked by calculating the Op---Op bond distance six ways; the values ...
The vapor-phase infrared and Raman spectra of p-difluorobenzene (h4) and (d4)
(Elsevier, 1985-04)
This new study of the vapor-phase infrared and Raman spectra of p-difluorobenzene (h4) and (d4) includes assignments from the high-resolution electronic spectrum, from fluorescence spectra, and one assignment from the two ...
