Oxygen Quenching Measurements for the S1 and S2 Fluorescence of Gas-Phase Fluoranthene

Autor: Russell H. Barnes, Lorenzo Sassu, William A. Ivancic, Busolo Wabuyele, Laura Perezzani

Publikováno v: Applied Spectroscopy. 55:307-310

The fluorescence emission of the fluoranthene molecule has been investigated at excitation wavelengths varying from 240 to 360 nm, and conducted from near collision-free conditions to atmosphericpressure conditions. The oxygen quenching rate for the

Nitric oxide measurements in a flame by laser fluorescence

Autor: Daniel R. Grieser, Russell H. Barnes

Publikováno v: Applied optics. 19(5)

Laser fluorescence measurements have been performed to detect nitric oxide in a CH(4)-O(2)-N(2) flame at atmospheric pressure. For these measurements a frequency-doubled tunable dye laser was used to excite the UV gamma-bands of nitric oxide. Sensiti

On-Line Coal Slurry Analyzer

Autor: H. Nicholas Conkle, Russell H. Barnes

Publikováno v: Coal Preparation. 11:87-102

Today most coals cleaned by advanced or conventional techniques are processed in an aqueous slurry. To optimize cleaning efficiency and better control cleaning operations, more rapid feedback on the coals' ash ad sulfur content (while still in the sl

Effects of spectral resolution on the identification of specific chemical compounds within complex spectral signatures

Autor: John P. Kurmer, John M. Collier, Busolo Wa Wabuyele, Russell H. Barnes

Publikováno v: SPIE Proceedings.

This paper presents preliminary results on the effects of spectral resolution and atmospheric transmission on the recovery of species concentrations using Partial Least Squares procedures. The effects of different levels of random spectral noise on t

Micro-Diffuse Reflectance and Matrix Isolation Fourier Transform Infrared Techniques for the Identification of Tetrachlorodibenzodioxins

Autor: Sidney Bourne, Charles J. Riggle, J. W. Brasch, Donald F. Gurka, Russell H. Barnes

Publikováno v: Applied Spectroscopy. 40:978-991

Micro-diffuse reflectance Fourier transform infrared (DRIFT) and matrix isolation (MI) Fourier transform infrared spectra of the 22 tetrachlorodibenzodioxin (TCDD) isomers have been recorded. The DRIFT and MI techniques required about four minutes an
