Excited state molecular structural evolution and chemical reactivity studied by femtosecond stimulated Raman spectroscopy

Creator:: Han, Fangyuan
Abstract:: In this dissertation, my research work on excited state dynamics of small organic molecules in solutions is presented. Using femtosecond stimulated Raman spectroscopy (FSRS) as the main experimental tool, the excited state hydrogen-bonding dynamics (ESHBD) of Coumarin 102, a common laser dye molecule, in ethanol solution is examined with <150...

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...

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...

Coherent anti-stokes raman spectroscopy of transient species

Creator:: Triggs, Nancy E.
Abstract:: The CARS apparatus at OSU was modified to permit studies in the 0-500 cm⁻¹ spectral region. The new low frequency capabilities were then used to study molecular clusters formed in free expansion jets of carbon dioxide. A strong cluster band was observed at 73 cm⁻¹, with a weaker shoulder at...

Coherent anti-Stokes Raman spectroscopy of gases

Creator:: Guthals, Dennis Marc
Abstract:: The development and applications of a 0.2 cm⁻¹ resolution Nd-YAG laser powered coherent anti-Stokes Raman spectroscopy, CARS, spectrometer for gas phase studies is chronicled in this thesis. Applications including CARS lineshape analysis, resonant CARS, and CARS of transient species and excited state molecules is reported. The intensity of the signal...

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...

Investigating Low-Frequency Vibrations in Condensed Matter Using Time-Resolved Third-Harmonic Generation Spectroscopy

Creator:: Wang, Liang
Abstract:: In this thesis, I present a new method we developed to study low frequency (< 700 cm⁻¹) vibrational dynamics: Time-resolved third-harmonic generation (TRTHG) spectroscopy. Among a variety of vibrational spectroscopy techniques, TRTHG differentiates itself with robustness, versatility, and simplicity. In TRTHG experiment, that involves only two ultrashort laser pulses, the...
