Application of Deuterium Isotope Effects on NMR Parameters as a Method of Intramolecular Hydrogen Bond Characterization in Enolic Forms of 1,3-diketones in the Solid State
DownloadFall 2022
The application of deuterium isotope effects on 13C NMR chemical shifts to study the nature of intramolecular hydrogen bonding in the enolic forms of two 1,3-diketones, tetraacetylethane (TAE) and avobenzone, in the solid state is reported. Carbon-13 NMR spectra of natural abundance TAE and...

Design and Fabrication of Micro-electro-mechanical Systems Actuators for Application in External Cavity Tunable Lasers
DownloadFall 2014
The limited availability of rugged and economical infra-red laser sources that can be tuned over a certain wavelength range is still a bottleneck for widespread application of spectroscopic methods to environmental, industrial, and medical trace gas monitoring. Conventional semiconductor lasers...

Development of a Mid-infrared Detection System for Real-time Measurements of Gas Phase Benzene, Toluene, Ethylbenzene and Xylenes using a Tunable External Cavity Quantum Cascade Laser
DownloadSpring 2012
The chemical transformation of trace gases, including reactions that result in aerosol particle formation, as well as the composition of the atmosphere deeply influence air quality and Earth's global climate. Use of a simulation chamber to study smog formation is a common method to investigate...

From the Pre-critical Nucleus to Atmospheric Aerosol Particles: Insights from Rotational Spectroscopic, Computational, and Aerosol Characterization Studies
DownloadFall 2024
Over the past several years in Alberta, the frequency and severity of wildfires has increased and resulted in the loss of lives, destruction of housing, and devastation of large forest areas. A byproduct of these fires are toxic emissions that contain primary aerosols and volatile organic...
