(Texas A&M University. Libraries, 1980)[^252]Cf-plasma desorption mass spectrometry is shown to be an excellent method for the analysis of chlorophylls in aggregated states. Investigation provide experimental evidence for the view that chlorophylls can be ...
-
(Texas A&M University. Libraries, 1980)A new method of determining the base sequence, the purity and the molecular weight of a chemically protected ribo- or deoxyribooligonucleotide is described. Using the method ²⁵²Cf-plasma desorption mass spectrometry positive ...
-
(Texas A&M University. Libraries, 1982)The natures of adsorption sites on La(,2)O(,3), Nd(,2)O(,3), and selected praseodymium oxides were investigated by examining surface reactions of probe molecules using computerized transmission infrared (IR) spectroscopy ...
-
(Texas A&M University. Libraries, 1983)The nature of the active sites for ethane dehydrogenation over chromium supported on silica gel and the effect of the support on the properties of chromium catalysts for the dehydrogenation of ethane were investigated. Low ...
-
(Texas A&M University. Libraries, 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 ...
-
(Texas A&M University. Libraries, 1985)Trace elements exert their influences through specific trace element compounds interacting with biologically important molecules in organisms. The identities and concentrations of trace element compounds must be known ...
-
(Texas A&M University. Libraries, 1977)Infrared spectroscopy was used to examine the surface properties of catalytic La₂Og₃ and a 1:1 mixture of LaOCl + La₂Og₃. Spectral studies of the dehydration/rehydration of the La(OH)₃/La₂O₃ system revealed the existence ...
-
(Texas A&M University. Libraries, 1986)The isotope shifts and hyperfine structure splittings of nine stable xenon isotopes in the mass range from 124 to 136 have been measured using the electronic transition 5d⁴D[subscript 7/2] - 6p⁴P⁰ [subscript 5/2] in the ...
-
(Texas A&M University. Libraries, 1986)The C1Пu state of H2 has a small hump in its potential due to the combination of an intermediate molecular attractive force and a long range repulsive van der Waal's force. This hump is large enough to allow the formation ...
-
(Texas A&M University. Libraries, 1976)A series of polypyrazolylborato and tetraphenyl compounds have been studied by x-ray crystallography. The structure of (diphenyldipyrazolylborato) (2-methylallyl) (dicarbonylmolybdenum) has been determined. The molybdenum ...
-
The synthesis and characterization of some dimethylarsinous acid esters of thio- and selenogalactose (Texas A&M University. Libraries, 1977)A series of galactose derivatives containing the -XAs(CH₃)₂ moiety u (X = S, Se) has been prepared. These are 2 ,3 ,4 ,6-tetra -0 -acetyl-1 -Sdimethylarsino-l-thio- β-D-galactopyranose, 2 ,3 ,4 ,6-tetra-O-acetyl-1 ...

-
(Texas A&M University. Libraries, 1978)A detailed NMR study has been made into the preparation, structure and characterization of a series of 1,7,7-trimethyl-2,3-benzobicyclo[3.3.1]non-2-enes. This family of compounds was derived from the parent structure, A, ...
-
(Texas A&M University. Libraries, 1978)In order to gain further insight into the forces governing the conformation of cyclobutane and its analogs, the molecules 1,3-disilacyclobutane and 1,3-disilacyclobutane-1,1,3,3-d₄ were prepared and studied for the first ...
-
(Texas A&M University. Libraries, 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 ...
