High Resolution Infrared Spectra of Carbon Dioxide Solvated with Helium Atoms
Infrared spectra of He -CO clusters with up to about 20 have been studied in the region of the CO fundamental band (2350 ) using a tunable diode laser spectrometer and pulsed supersonic jet source with cooled ( C) pinhole or slit nozzles and high backing pressures ( atm). Compared to previous studies of He -OCS [1] and -N O [2] clusters, the higher symmetry of CO results in simpler spectra but ...
متن کاملHigh Resolution Near-Infrared Spectra of Protostars
We present new high resolution (R ≃ 21, 000) near-infrared (λ = 2μm) spectroscopic observations of a sample of Class I and flat-spectrum protostellar objects in the ρ Ophiuchi dark cloud. None of the five Class I spectra show CO v = 0 – 2 absorption features, consistent with high K-band continuum veilings, 4 . rk . 20 and fast stellar rotation, assuming that the underlying protostellar photosph...
متن کاملInfrared 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 ...
متن کاملHigh resolution atmospheric monitoring of urban carbon dioxide sources
[1] Estimates of fossil fuel emissions on local to regional spatial scales and hourly to weekly temporal scales are increasingly useful in studies of the carbon cycle and mass and energy flow in cities. We used a tunable diode laser absorption spectrometer (TDL) to measure CO2 mixing ratios and carbon isotope composition of CO2 in order to estimate the contribution of gasoline versus natural ga...
متن کاملInfrared spectra of carbon nitride films
The assignment of the vibrational modes in amorphous carbon nitride (CN) films is discussed by considering CN films deposited using a variety of methods. The infrared (IR) spectra of CN show three main absorption bands. In hydrogenated CN samples, CH and NH groups give rise to stretching vibrations at 3000 and 3400 cm , respectively. A weaker sharp band is y1 x x observed approximately 2200 cm ...
