Collisional Quenching Dynamics and Reactivity of Highly Vibrationally Excited Molecules
(2008-11-13)
Highly excited molecules are of great importance in many areas of chemistry including photochemistry. The dynamics of highly excited molecules are affected by the intermolecular and intramolecular energy flow between many ...
OPTICAL KERR EFFECT SPECTROSCOPY OF SIMPLE LIQUIDS
(2009)
Optical Kerr effect (OKE) spectroscopy has become a prominent nonlinear optical technique for studying liquids, which allows for the direct, time-resolved probing of collective orientational diffusion as well as Raman-active ...
The role of the F spin-orbit excited state in the F+H2 and F+HD reactions
(2004-07-22)
In this dissertation we study the role of the F spin-orbit excited state (F*) in the F+H2 and F+HD reactions using quantum mechanical calculations. The calculations involve multiple potential energy surfaces (the ...
STRUCTURE TAILORED PROPERTIES AND FUNCTIONALITIES OF ZERO-DIMENSIONAL NANOSTRUCTURES
(2009)
The field of nanoscience and nanotechnology has achieved significant progress over last thirty years. Complex nanostructures with tunable properties for novel applications have been successfully fabricated and characterized. ...
AQUEOUS PHOTOCHEMISTRY OF 1,4-BENZOQUINONES AND THEIR POSSIBLE ROLE IN THE PHOTOCHEMISTRY OF NATURAL ORGANIC MATTER
(2005-01-13)
Past research implicated the presence of an organic species as a photochemical source of OH radical in natural waters. Quinones were postulated to be one of the possible OH sources due to 1) the ubiquitous occurence of ...
Synthesis, Characterization and Catalytic Properties of Bimetallic Nanoparticles
(2009)
Due to the ever-increasing desire for catalysts that possess high activities and selectivities for industrially relevant reactions, much effort is being spent on the synthesis of mono and bimetallic nanoparticles with ...
ARCHITECTURE-ELECTRONIC PROPERTY RELATIONS ACROSS MOLECULAR SEMICONDUCTOR INTERFACES
(2010)
Multicomponent organic films have increasing applications in photovoltaic technologies and other electronic devices. These applications depend strongly on the structural and electronic properties of the heterojunctions. ...
INTERFACIAL SOLVATION AND EXCITED STATE PHOTOPHYSICAL PROPERTIES OF 7-AMINOCOUMARINS AT SILICA/LIQUID INTERFACES
(2010)
The properties of solutes adsorbed at interfaces can be very different compared to bulk solution limits. This thesis examines how polar, hydrophilic silica surfaces and different solvents systematically change a solute's ...
LINK BETWEEN DYNAMICS AND FUNCTION IN SINGLE AND MULTI-SUBUNIT ENZYMES
(2010)
Biopolymers, such as proteins and DNA, are polymers whose three-dimensional
conformations dene their biological functions. Current emphasis on structures has
greatly advanced our understanding of the functions of ...
Visible Light Photorelease of Carboxylate Anions by Mediated Photoinduced Electron Transfer to Pyridinium-based Protecting Groups
(2009)
The use of sensitized photoinduced electron transfer (PET) to trigger release of redox-active photoremovable protecting groups (PRPGs) allows a broad range of chromophores to be selected that absorb in difference wavelength ...
