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...

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...

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...

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...

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...

Applications of nonlinear raman spectroscopy

Creator:: Melin, Stéphanie
Abstract:: Two nonlinear optical experiments are presented in which the third-order electronic susceptibility of molecules is used to generate Raman signals. The first one uses a single 532 nm beam from a Nd:YAG laser to produce Stimulated Raman Scattering in benzene and deuterated benzene. With a simple experimental set-up, stimulated emission...
