Chemical graphs--V : Enumeration and proposed nomenclature of benzenoid cata-condensed polycyclic aromatic hydrocarbons
(Elsevier, 1968)
A modified definition is proposed for cata-condensed aromatic hydrocarbons. A formula is devised for the number of isomers of non-branched cata-condensed arenes in function of the number of hexagons. Proposals are made for ...
Spectroscopic studies of Lewis acid-base complexes--I : Vibrational spectra and assignments for trimethylymine complexes of boron halides
(Elsevier, 1964-10)
Infrared and Raman spectra of 1:1 complexes of trimethylamine with boron trifluoride, boron trichloride and boron tribromide have been obtained in the solid state. Samples studied included those isotopically enriched in ...
Vibrational spectra and assignments for (CH3)2NPF2
(Elsevier, 1965-07)
Infrared and Raman spectra of dimethylaminodifluorophosphine have been obtained for the gaseous and liquid states at room temperature and for the solid at low temperature. Vibrational assignments are proposed based on a Cs, model.
The hydrogen-deuterium exchange reaction on cobalt ferrite
(Elsevier, 1963-08)
The catalytic activity of cobalt ferrite, Co3-xFexO4, for the hydrogen-deuterium exchange reaction and the change in thermoelectric power of the ferrite during the adsorption of hydrogen and oxygen were investigated as ...
Roman spectrum and vibrational assignments for the trifluoroacetate ion
(Elsevier, 1962-08)
Surface chemistry of active carbon: Specific adsorption of phenols
(Elsevier, 1969-09)
The characteristics of the uptake of phenol and nitrophenols by active carbon have been investigated. The measurements of solution equilibrium parameters as well as surface structural characteristics determined by infrared ...
Magnetite (Fe3O4) Heat capacity and thermodynamic properties from 5 to 350 K, low-temperature transition
(Elsevier, 1969-11)
The heat capacity of synthetic Fe3O4 has been measured over the range from 5 to 350 K. Values of thermodynamic functions have been calculated and Cp, So, and (Ho - H0o)/T at 298.15 K are 36.04, 34.93, and 19.85 cal mol-1 ...
