Vibration-rotational studies of isotopic variants of diatomic molecules

Creator:

Orlov, Mikhail L.

Resource Type:

Dissertation
Nonlinear Raman spectroscopy of gases

Creator:

Lundeen, Thomas F.

Abstract:

Applications of several methods of coherent nonlinear Raman Spectroscopy have been made in this thesis research. The theory and potential of one of these, Photoacoustic Raman Spectroscopy (PARS), is discussed in chapter two. Experimental results are presented which illustrate the sensitivity of this method and establish sampling conditions for maximum...

Nonlinear Raman spectroscopy in supersonic jets

Creator:

Pubanz, George A.

Abstract:

The techniques of coherent anti-Stokes Raman spectroscopy (CARS) and inverse Raman spectroscopy (IRS) are used to examine carbon dioxide aggregation in a supersonic jet expansion. To promote the formation of small clusters, a BMW injector valve is modified to permit its use as a pulsed nozzle at very cold temperatures....

High resolution stimulated raman spectroscopy

Creator:

Beck, Rainer D.

Abstract:

The high resolution stimulated Raman spectrometer at OSU was modified to improve its sensitivity and to extend its range of applications to low Raman shifts and to the spectroscopy of solids and liquids. As part of the characterization of the spectrometer, optical Stark effects on rotational and vibrational transitions of...

High resolution spectroscopy of sulfur trioxide and carbon suboxide

Creator:

Masiello, Tony

Abstract:

High resolution spectroscopy was used to study the properties of two simple polyatomic molecules, sulfur trioxide, SO₃, and carbon suboxide, C₃O₂. The fundamental modes and several hot bands of the ¹⁸O isotopic fonns of SO₃ (³²S¹⁸O₃ and ³⁴S¹⁸O₃) have been investigated using both infrared spectroscopy and coherent anti-Stokes Raman scattering...

High resolution ionization-detected simulated Raman spectroscopy

Creator:

Crew, Marshall D.

Abstract:

A new experimental apparatus was built at Oregon State University to perform high resolution stimulated Raman spectroscopy in a pulsed molecular jet at state densities of the order of 10¹¹ cm⁻³. The technique uses a stimulated Raman step to first populate a vibrational/rotational level and then a resonantly enhanced multiphoton...
