High Resolution Optical Spectroscopy
This experiment will allow you to learn a specific optical technique with applications over a wide variety of phenomena. You will use a commercial spectrometer (a very common piece of equipment in research labs) to obtain the emission wavelengths of particular elements (e.g. mercury, sodium, hydrogen and deuterium) as well as to compare the outputs of gas and solid state lasers. You will be abl...
متن کاملComputer Simulations of High Resolution NMR Spectra
The evolution of a spin system during the application of an RF pulse is a central aspect of high resolution NMR spectroscopy. An appropriately applied field can lead to saturation or decoupling effects. When a field is used to maintain a spinlocked condition, both scalar and dipolar interactions come into play, leading to coherence transfers and nuclear Overhauser effects that form the basis of...
متن کاملAutomatic abundance analysis of high resolution spectra
We describe an automatic procedure for determining abundances from high resolution spectra. Such procedures are becoming increasingly important as large amounts of data are delivered from 8m telescopes and their high-multiplexing fiber facilities, such as FLAMES on ESO-VLT. The present procedure is specifically targeted for the analysis of spectra of giants in the Sgr dSph; however, the procedu...
متن کاملHigh resolution X-ray spectra of quasars
Past X-ray observations by ASCA suggest that warm absorbers (Ovii and Oviii edges) are apparently rare in high luminosity AGNs (quasars) while they are more common in low luminosity AGNs (Seyferts). However, this could be a selection effect if high luminosity AGNs have mostly narrow absorption lines (with no strong bound free edges), which escaped detection by the low resolution of ASCA. To che...
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...
