Two-photon excitation spectroscopy of some polynuclear aromatic compounds
(1985)
Two-photon excitation spectra were taken for the following compounds: phenanthrene, 3,4-benzophenanthrene, triphenylene, chrysene, pyrene, and tetracene. The samples were dissolved in n-alkane solvents and the spectra were ...
Studies directed toward stereoselective synthesis of 1,3-amino alcohols via intramolecular amidomercuration
(1985)
The cyclization of the benzyl carbamate of 6-hepten-2-amine (31) with mercuric trifluoroacetate in nitromethane over a period of 20 h afforded, after borohydride reduction of the organomercurial, the benzyl carbamate of ...
Extreme ultraviolet beam-foil spectroscopy of highly ionized neon and argon
(1986)
A study of the extreme ultaviolet radiation emitted by ion beams of highly ionized neon and argon after passage through thin foils was conducted at the variable energy cyclotron at Texas A&M University. A grazing incidence ...
Methods for polynuclear aromatic hydrocarbon determination in air samples using polar-bonded phase HPLC and GC-MS with application to oil refinery samples
(1985)
The first part of this work deals with the development of accurate and reliable procedures for collection and analysis of polynuclear aromatic hydrocarbons (PNAs). The second part shows the application of these procedures ...
Characterization and electronic properties of transition-metal exchanged zirconium and titanium phosphate
(1980)
A series of transition-metal-ion forms of phosphates of quadrivalent elements having the general formula X^[IV]M(PO4)2*yH2O(S^[IV] = Zr or Ti; M = Cu(II), Co(II) and Ni(II)) have been characterized. The electronic absorption ...
Viscosities of some n-alkane liquid mixtures
(1985)
The viscosities and densities of selected non-electrolyte liquid mixtures was measured and the results compared with various theoretical models. The following mixtures were prepared: (1) a binary mixture of n-hexadecane + ...
