A Kinetic and Thermodynamic Study of Exciplex Fluorescence Quenching by Ion Pairs
… in solvents of low dielectric constant. Linear Stern-Volmer plots are obtained for quenching of both lifetime and intensity in dioxane. However, mechanistic complications are implied by intercepts exceeding unity and by the unequal slopes of these plots. Qualitatively similar behavior is …

Synthesis and Spectroscopic Studies of Substituted Pyrrolocytidines
… FRET pairs to be used as molecular beacons and Stern-Volmer plots were used to determine how effective each quencher was at reducing the fluorescence intensity of the fluorophores. The molar absorptivity of a 6-DABCYL mimic pyrrolocytidine was determined and compared with the universal quencher …

The synthesis and investigation of the electronic properties of crown ether, [2]-catenane, and [2]-rotaxane architectures
… 2, is presented with focus on interpreting Stern-Volmer plots.

Interactions of ferriprotoporphyrin IX with neutral lipids and detergents: insights into their role in β-haematin formation
… fluorescence quenching ability of Fe(III)PPIX, Stern-Volmer plots were generated to estimate the concentration of Fe(III)PPIX partitioned into Nile red stained neutral lipid droplets (NLBDs) over a pH range. The pH dependence was found to correlate with the charge of the Fe(III)PPIX molecule and …

Electrodeposited nanoparticles: properties and photocatalytic applications
… solution has been identified by analysis of the Stern-Volmer plots. The quenching of monolayers of these complexes by POW, coupled to the electrochemical regeneration of the ground state osmium complex by potential application at the FDTO electrode, has been used to photo-catalytically reduce …

INTERACTION OF POLYCYCLIC AROMATIC HYDROCARBONS WITH DISSOLVED AND SEDIMENT ASSOCIATED HUMIC MATERIALS (NMR, FLUORESCENCE)
… as a function of added humic material using Stern-Volmer plots. No separation is required and since the technique involves a ratio measurement the exact concentration of pollutant is not required. Anthracene-humic acid association constants normalized to the fraction of organic carbon in the …

New explorations in visible-light mediated energy and single electron transfer for nitrogen heterocycle synthesis
… reaction mechanisms presented are supported by Stern-Volmer plots as well as deuterium labelling studies. Finally, chapter four explores the synthesis of 2-azetidinones (β-lactams) from simple acrylamide starting materials by visible-light-mediated energy transfer catalysis. The reaction …

The spectroscopy and the photophysics of 1,2-benzazulene, a derivative of azulene.
… a static quenching component observed from the Stern-Volmer plots. The time-dependent diffusion coefficient (Kq) was obtained to be 1.5 x 1010 M-1s-1, similar to that obtained by Reis e Sousa, et al.1. Picosecond transient absorption measurement conducted on the solution phase samples of …

Design, Synthesis and Study of Novel Nucleobase Analogs
This thesis focused on nucleobase modified peptide nucleic acid (PNA) and DNA to expand the repertoire of available nucleobase analogs used in the study of nucleic acids. More specifically, we are interested in modification of the nucleobases such that they retain their ability to undergo …
