Design, characterization, and application of spectrometers for determination of low-level dissolved oxygen with small-volume sampling methodology

Creator:

Cakin, Defne

Abstract:

New analytical methods and instrumentation were developed for the determination of dissolved oxygen (DO) at low concentrations in water. The methods were based on monitoring the absorbance increase due to the oxidation of reduced indigo carmine (IC) by oxygen in the sample in different types of spectrometer cells. Spectrophotometer cells...

Polarization spectroscopy and photodissociation studies of nitroaromatic compounds in the gas phase

Creator:

Abbott, James E.

Abstract:

The central purpose of this dissertation was to explore and expand the use of an uniform electric field for orientation and for subsequent spectroscopic investigation of asymmetric polar molecules in the gas phase. The systems of study were nitrobenzene (NB) and the nitrotoluene (NT) isomers. We were able to quantitatively...

Development, validation and the application of a congener specific photodegradation model for PBDEs

Creator:

Zeng, Xia

Abstract:

The thermodynamic properties of 39 PBDEs have been calculated using Gaussian 03 on the B3LYP/6-31G(d)//B3LYP/6-31G(d) level. The PBDE congeners' enthalpies of formation increase with increasing number of bromines and show a strong dependence on the bromine substitution pattern. The effects of bromine substitution pattern have been quantitatively studied by GAM...
