Infrared Spectra of Polybutadiene Monoxide

Vibrational spectra of small silicon monoxide cluster cations measured by infrared multiple photon dissociation spectroscopyw

The first gas-phase infrared spectra of silicon monoxide cations (SiO)n , n = 3–5, using multiple photon dissociation in the 550–1250 cm 1 frequency range, are reported. All clusters studied here fragment via loss of a neutral SiO unit. The experimental spectra are compared to simulated linear absorption spectra from calculated low energy isomers for each cluster. This analysis indicates that a...

Infrared Absorption and Emission Spectra of Carbon Monoxide in the Region from 4 to 6 Microns

The infrared absorption and emission spectra of carbon mon ox idc a nd carbo n dioxide have been m easured with high resolution in the regi on from 4 to 6 microns. The m easurem ents of the Cl2016 fundamental band were carried out to a high precision, a nd a set of m olecu lar constants were calculated from the experimental data. In emiss ion the 10 and 2-1 bands of CO were measured in the P br...

Vibrational spectra of small silicon monoxide cluster cations measured by infrared multiple photon dissociation spectroscopy.

The first gas-phase infrared spectra of silicon monoxide cations (SiO)(n)(+), n = 3-5, using multiple photon dissociation in the 550-1250 cm(-1) frequency range, are reported. All clusters studied here fragment via loss of a neutral SiO unit. The experimental spectra are compared to simulated linear absorption spectra from calculated low energy isomers for each cluster.

Near-Infrared Spectra of Ultraluminous Infrared Galaxies.

Near-infrared spectra with a resolution of lambda&solm0;Deltalambda approximately 1100 in the rest-wavelength range of 1.8-2.2 µm have been obtained for a complete sample of 33 ultraluminous infrared galaxies (ULIRGs). Of the 33 objects observed, two show evidence of a central active galactic nucleus (AGN) through either a broad Paschen-alpha line or emission in the 1.963 µm fine structure of [...
