As the number of atoms in a cluster system increases, the number of local minima on the Born-Oppenheimer potential energy surface is expected to increase …
The primary objective of this thesis is the development of methods to generate and detect local phonons in aqueous solutions, which lead to new understanding …
What defines the intrinsic dynamics of liquids? By studying the hard sphere liquids, whose potential energy landscape is so singular that traditional landscape approaches do …
Aqueous phase transitions within multi-walled carbon nanotubes (MWCNTs) were studied as a function of temperature, time and chemical functionalization via X-ray Spatial Frequency Heterodyne Imaging …
Nitrogen oxides (NOx=NO+NO2) play a key role in atmospheric chemistry, contributing to production of ground-level ozone, aerosol chemistry, and acid deposition through the conversion to …
In this thesis, we use the large deviations principle to characterize the rate of convergence of the empirical measures of Markov processes. An explicit formula …
Our central goal in this thesis is to investigate the vibrational energy relaxation (VER) of perylene in solution. The size of a perylene molecule makes …

The research discussed in this thesis is a theoretical and experimental analysis of the pyrometer based on the photoacoustic effect. For the pyrometer based on …
This thesis examines thermodynamic properties for polycyclic aromatic compounds (PACs) and brominated flame retardants (BFRs). Hundreds of thousands of anthropogenic organic chemicals have been produced …
This thesis describes an experimental investigation of the photoacoustic effect generated by laser initiated exothermic chemical reactions. Experiments were carried out to determine the influence …
This thesis describes five theoretical and experimental projects completed during my Ph.D studies. <br/><br/> The first chapter provides theoretical results for the photoacoustic effect in a …
Research in this thesis discusses photoacoustic generation and its application. Theoretical calculations are carried out for different photoacoustic models (thin film model, moving source model) …
Studying complex dynamics of a many-body problem is an unpleasant task considering the dependence of the system's motions on the rugged high-dimensional potential energy landscape. …
Photochemical electrocyclic reactions have a long history of capturing the curiosity of scientists across disciplines. Especially the mechanisms leading to their high stereospecificity and the …
Many molecular relaxation processes, such as internal conversion, intramolecular vibrational relaxation, charge transfer and isomerization are accompanied by changes of the molecular geometrical structures. Studies …
Rydberg Fingerprint Spectroscopy (RFS) has been deftly applied to small molecules and shown exquisitely sensitive to global molecular structure. This has stimulated interest in its …
This thesis describes three sensitive detection projects focusing on the photoacoustic regeneration in gases, the electrokinetics of colloidal jets, and the infrared thermography of aqueous …
Chemical reactions of the early actinide elements in aqueous solution are complex and challenging to predict. Quantitative models of actinide reactions must overcome several obstacles. …
