Sanchez-Gonzalez, Rodrigo (2012-07-16)The study of high-speed flows represents a challenging problem in the fluid dynamics field due to the presence of chemical reactions and non-equilibrium effects. Hypersonic flights, where speeds reach Mach 5 and above, are ...
-
Application of Advanced Laser and Optical Diagnostics Towards Non-Thermochemical Equilibrium Systems Hsu, Andrea G. (2010-07-14)The Multidisciplinary University Research Initiative (MURI) research at Texas A and M University is concerned with the experimental characterization of non-thermal and non-chemical equilibrium systems in hypersonic (Mach ...

Pickard, James Morgan (Texas A&M University. Libraries, 1976)The gas phase reaction of 1,1-difluoroethylene with bromine was studied over the temperature range 550 to 620°K. The experimental data, derived from the early stages of reaction, were found to be consistent with the following ...
-
Ohlsen, James Raymond (Texas A&M University. Libraries, 1977)The colored species (λ[subscript max] ~ 500 nm) formed form the reaction of nitric oxide with Lewis acids (BF₃, BCl₃, SiF₄, TiCl₄, and SnCl₄), SO₂, or HCL at 77°K has been characterized by resonance Raman and infrared ...
-
DelliSante, Gregory Noel (Texas A&M University. Libraries, 1982)The natures of adsorption sites on La(,2)O(,3), Nd(,2)O(,3), and selected praseodymium oxides were investigated by examining surface reactions of probe molecules using computerized transmission infrared (IR) spectroscopy ...
-
Cortez, Enriqueta (Texas A&M University. Libraries, 1994)The far-infrared and low-frequency Raman spectra of 1,3-Dioxole have been analyzed. The gas-phase far-infrared spectrum shows a series of eleven singlequantum- jump and three triple-quantum-jump transitions in the 40-330 ...
-
Rosas, Rebecca Lee (Texas A&M University. Libraries, 1990)Semi empirical computational methods can be used in conjunction with low frequency infrared and Raman spectra of gas -phase molecules to obtain information about large amplitude vibrations which are important for understanding ...
-
Pacheco, Jorge Luis (Texas A&M University. Libraries, 1987)The use of laser-excited fluorescence spectroscopy has generated interest as a technique for the measurement of atomic trace concentrations in heterogeneous flame systems. Under saturation of the radiatively excited level ...
-
Geoffroy, Katherine Ann (Texas A&M University. Libraries, 1977)The amount of angular momentum dissipated during the particle emission and photon emission stages of the deexcitation of the compound nuclei formed in the reactions of 107, 155, and 197 MeV ¹²C ions with ²⁷A1 and with ...
-
Winters, James Curtis (Texas A&M University. Libraries, )The electron paramagnetic resonance spectra of lumiflavin (LF), Flavin mononucleotide (FMN), and riboflavin (RF) anion radicals in alkaline aqueous solutions of sucrose, dextrose hydrate, and glycerol have been recorded. ...
-
Thompson, Jonathan Verl (2017-04-20)Optical methods have become an integral part of today’s sensing and spectroscopic techniques. These techniques provide many tools that are used for research, security, safety and health. However, attenuation effects, like ...
-
Kim, Hahkjoon (Texas A&M University, 2006-08-16)This dissertation focuses on the photodissociation dynamics of stratospheric bromine and chlorine radical intermediates (BrO, ClO) along with reservoir species (ClONO2), which are known to play an important role at ...
-
Cooke, Joel Midleton (Texas A&M University. Libraries, 1979)In an attempt to determine the forces responsible for the conformations of small ring molecules the spectra of a series of ring molecules have been recorded and analyzed. Theoretical calculations were carried out to determine ...
-
Villarreal, John Ricardo (Texas A&M University. Libraries, 1976)The conformations of several cyclic and bicyclic molecules were investigated through interpretation of their infrared and Raman spectra. The molecular systems included cyclopentene and three deuterated derivatives, a series ...
-
Qu, Xinmei (2009-05-15)The dissociation of a 199Hg2 dimer prepares an entangled state of two spatially separated 199Hg atoms, each with nuclear spin 1/2, and with zero total electron and nuclear spin angular momenta. This is identical to the ...
