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.

IR-REMPI Double Resonance Spectroscopy: The Near-IR Spectrum of NO−Ar Revisited

The Journal of Physical Chemistry A, 2008
We describe a new approach to IR-UV double resonance spectroscopy of NO-containing van der Waals complexes. The basic idea combines REMPI detection through a hot band transition with a simultaneous frequency scan of the IR and UV lasers in such a way that the combined photon energy is kept constant throughout the scan, matching a UV resonance ...

Near-IR electronic absorption spectrum of ONCN

Chemical Physics Letters, 1984
Abstract A partial analysis of the rotational structure of a few bands of the 1 A″ ← 1 A′ transition of nitrosyl cyanide is presented. A preliminary model for the bending potential function for these Renner components is discussed.

The IR spectrum of Pu(IV) polymer

Journal of Inorganic and Nuclear Chemistry, 1978
Abstract The IR spectrum of Pu(IV) polymer has been measured from 200–4000 cm −1 . Major bands which could be associated directly with the oxygen-bridged polymer occured at 360 and 3400 cm −1 . These were assigned, respectively, to a PuO vibration similar to the lattice vibration of high-fired PuO 2 and to an OH stretching vibration of a water ...

Li2HPO3, H2O: Crystal Structure and IR Spectrum

Journal of Chemical Crystallography, 2010
Crystal structure of Li2HPO3,H2O was determined by single-crystal X-Ray diffraction analysis at 173(2) K. It crystallizes in the monoclinic system (P21/c) with the parameters: a = 5.0322(9) A, b = 8.9795(17) A, c = 17.088(4) A, β = 92.672(16)° and Z = 8. The structure was refined to R = 0.0237 and ωR = 0.0650 for 1449 reflexions.

The collisionless IR absorption spectrum of C3F7I

Chemical Physics Letters, 1986
Abstract The collisionless infrared absorption spectrum of C3F7I was measured with an 80 ns CO2 laser system. Comparison with the collisional absorption spectrum reveals that collisions induce a red-shift as well as significant broadening of the collisionless spectrum.

Near-IR Absorption Spectrum of Aromatic Excimers

The Journal of Physical Chemistry A, 1997
The absorption spectrum of excimers in fluid media has been measured with 1-methylnaphthalene, anthracene, pyrene, and perylene. In all compounds studied an absorption band characteristic of an excimer has been observed in the near-IR. It is shown that the IR band can be understood by assuming that an excimer is essentially a charge-transfer complex ...
