Ir spectrum of dinitrosyldicarbonyliron

Journal of Molecular Structure, 1969
Abstract An analysis of the vapour and liquid spectra of Fe(CO)2(NO)2 in the range 5000-250 cm−1 has led to an assignment of all the fundamental vibrations. A normal-coordinate treatment has been carried out using a diagonal symmetry force field on the basis of a C2v symmetry model for the molecule.

The IR spectrum of the double QSO

Nature, 1980
The hypothesis that the double QSO, 0957 + 561A,B (separation 6 arcs s and z = 1.4) is formed by a gravitational lens1 has found strong support from observations2 suggesting the presence of an intervening giant elliptical galaxy with z ≃ 0.4, separated from component B by

IR absorption spectrum of thiohydantoin

Soviet Physics Journal, 1970
The IR absorption spectrum of thiohydantoin is found in the range 400–3500 cam−1, and the normal-mode frequencies are calculated on the basis of a model. The IR spectrum is interpreted on the basis of the theoretical results, the experimental x-ray spectrum, and the microwave dielectric constants.

Theoretical study of silsesquioxane organometallic complex structure and IR spectrum. II Interpretation of the IR spectrum

Journal of Molecular Structure, 1998
Abstract On the basis of the parameters identified in the first paper of this series of two, the spectral distribution curves of the absorption coefficient in the IR spectral interval for a silsesquioxane organometallic complex were calculated. Good agreement with experimental data was obtained.

Analysis of glucopyranoside trinitrate IR spectrum

Journal of Applied Spectroscopy, 2008
The IR spectrum of 4-O-methyl-2,3,6-tri-O-nitromethyl-β-D-glucopyranoside has been interpreted in detail for the first time based on complete calculation of the normal vibration frequencies and absolute intensities of its IR absorption bands and a comparison of them with the corresponding experimental data. The results indicate that the location of the

IR absorption spectrum of hydrogen xanthane

Soviet Physics Journal, 1970
The normal vibration frequencies of hydrogen xanthane are calculated on the basis of a mechanical model. The IR absorption spectrum was measured in the range 400–3600 cm−1 for tablets of this substance with KBr and in vaseline and fluorinated oil. The spectrum is interpreted.

Novel Waveplate Designs For The IR Spectrum

SPIE Proceedings, 1989
Infrared optical systems, including ellipsometers and sensors, make frequent use of traditional waveplate technology. In some cases, the limited spectral bandwidth associated with conventional IR waveplates has limited the wavelength range over which these systems can perform.
