Far infrared absorption spectra of 4 isotopes of methyl alcohol.

Far infrared Spectra of La1-xCaxMn0.9Li0.1O3

Highly correlated ab initio study of the far infrared spectra of methyl acetate.

Highly correlated ab initio calculations (CCSD(T)) are used to compute gas phase spectroscopic parameters of three isotopologues of the methyl acetate (CH(3)COOCH(3), CD(3)COOCH(3), and CH(3)COOCD(3)), searching to help experimental assignments and astrophysical detections. The molecule shows two conformers cis and trans separated by a barrier of 4457 cm(-1). The potential energy surface presen...

Infrared Absorption Spectra of Steroids (an Atlas)

comments (p. 82), "Apr's de publications initiales optimistes, ont succede des rapports negatifs." In the introduction, it becomes clear that French laboratory methods are much like ours. The Lee-White method and the Quick test are standard procedures. On the other hand, the Continental workers seem to place more emphasis than we do on the in vitro heparin tolerance. Later portions of the book ...

Far-infrared Absorption by Small Particles

Detailed far-infrared (FIR) and mid-infrared (MIR) studies of aluminum small particles have been carried out. MIR absorption studies of clustered and non-clustered samples suggest that the anomalous FIR absorption does not arise from the clustering together of the individual metallic particles. The MIR absorption, which is too small to be the continuation of the anomalous FIR absorption, could ...

Mechanism of the far-infrared absorption of carbon-nanotube films.

The far-infrared conductivity of single-wall carbon-nanotube ensembles is dominated by a broad absorption peak around 4 THz whose origin is still debated. We observe an overall depletion of this peak when the nanotubes are excited by a short visible laser pulse. This finding excludes optical absorption due to a particle-plasmon resonance and instead shows that interband transitions in tubes wit...
