Quantification of benzo[a]pyrene-diol-epoxide adducts by laser-induced fluorescence spectroscopy
… project has focused on the development of new laser-induced fluorescence (LIF) based methods for the quantification of adducts in human samples. Two new instruments were built for LIF analysis. A cryogenic LIF instrument using a pulsed tunable dye laser as the excitation source was developed to …

Laser Chemical Vapor Deposition of Titanium Nitride and Process Diagnostics With Laser-Induced Fluorescence Spectroscopy
… on Ti-6Al-4V substrates by a cw CO$\sb2$ laser chemical vapor deposition (LCVD) process with TiCl$\sb4$, H$\sb2$, and N$\sb2$. Pulsed dye laser induced fluorescence (LIF) spectroscopy is used to obtain transient gas phase Ti atomic concentration above the substrate. Multi-wavelength …

A System For Conducting Laser-Induced Fluorescence Measurements On Gas Mixtures Exposed To Alpha Radiation
… to an existing vacuum system to allow laser-induced fluorescence spectroscopy measurements within simulated atmospheres under a variety of conditions. This added capability will expand the laboratory’s ability to experimentally validate a computational model that calculates the effects …

High resolution spectroscopy of some gaseous transition metal containing diatomic molecules
… at sub-Doppler resolution by intermodulated laser-induced fluorescence. The C³Π and e¹Π states, which belong to the same electron configuration (4dδ)¹(4dπ)¹, interact strongly with each other by a second-order spin-orbit/Fermi contact mechanism; the structure of the resulting e¹Π/ C³Π complex …

Sorption of Metals onto Natural Sediments and Engineered Iron Oxide Nanoparticles
… increasing phosphate addition. X-ray absorption spectroscopy (XAS) measurements of samples from the batch experiments found that U(VI) was predominantly adsorbed at conditions relevant to most field sites (low U(VI) loadings, < 25 µM), and U(VI) phosphate precipitation occurred only at high …

The Electronic and Vibrational Spectroscopy of Matrix-Isolated Phthalocyanines – Experiment and Theory
… their importance in industry, their optical spectroscopy has yet to be fully characterised. Low-temperature solids consisting of the rare gases or inert materials like nitrogen offer an ideal environment in which to study these molecules. The resulting spectral bands in inert cryogenic …
