Coupling pathways for dihydroxy aromatics during coal pyrolysis and liquefaction
Autor: S. Esther Nigenda, Gilbert A. St. John, Donald F. McMillen, Ripudaman Malhotra, Sou-Jen Chang
Publikováno v: Fuel. 83:1455-1467
Studies with model-compounds and hybrid studies in which model compounds are added to coal experiments were conducted to elucidate the major pathways by which phenols can lead to cross-links during coal conversion. This effort was greatly facilitated

Characterization of coal-liquefaction products by molecular-weight profiles produced by field-ionization mass spectrometry
Autor: Gilbert A. St. John, Michael Anbar
Publikováno v: Fuel. 57:105-110
Field-ionization mass spectrometry, which produces fragmentation-free mass spectra, is being applied to the analysis of coal-liquefaction products. Using a new highly efficient and sturdy field-ionization source, samples of various coal-liquefaction

Experiments on N2(A 3Σu+). III. Excitation of Hg
Autor: Gilbert A. St. John, Robert A. Young
Publikováno v: The Journal of Chemical Physics. 48:2572-2574
The rate coefficients of the reaction N2(A 3Σu+) + Hg→N2(X 1Σ) + Hg(3P10) have been measured for υ′ = 0 and 1 as k(0) = 8 × 10−12cm3 / sec and k(1) = 9 × 10−12cm3 / sec. The total rate coefficient for de‐excitation of N2(A 3Σu+) by Hg

Experiments on N2(A3Σu+). II. Excitation of NO
Autor: Robert A. Young, Gilbert A. St. John
Publikováno v: The Journal of Chemical Physics. 48:898-900
The rate coefficient for the process N2(A 3Σu+υ′ = 0, 1) + NO(X 2Π)→N2(X 1Σ) + NO(A 2Σ+υ′ = o) is measured to be 3 × 10−11 cm3/sec. Essentially half of all de‐exciting collisions of N2(A 3Σu+) with NO result in excitation of NO. The

Dissociation of N2 in Weak rf Discharge
Autor: Gilbert A. St. John, Robert A. Young
Publikováno v: The Journal of Chemical Physics. 49:3505-3507
It has been established that the production of nitrogen atoms from molecular nitrogen by a weak rf discharge is due predominantly to dissociation of a metastable state of N2 by electron impact.

Determination of Subpicogram Amounts of Chemical Agents in the Atmosphere. Phase 2
Autor: Gilbert A. St. John, Michael Anbar
During the second phase of this project, reported here, the objectives were to verify the sensitivity and determine the practical limits of field ionization detection of specific chemical warfare agents by a cross calibration procedure, to determine
