CNDO/2-CI calculations on aromatic hydrocarbons
(1970)
The CNDO/2 scheme is used to calculate the ground state wavefunctions for benzene, naphthalene, azulene, biphenylene, anthracene, phenanthrene, 1, 8 dimethylnaphthalene and 2, 3 dimethylnaphthalene. The core and resonance ...
Stereochemical studies of coordination complexes. : I. Spectropolarimetric titrations of metal ions using D-(-)-Trans-1,2-cyclohexanediaminetetraacetic acid. II. Optical rotatory dispersion and circular dichroism studies of transition metal complexes of stereospecific ligands
(1970)
A method is described for the spectropolarimetric titrations of the group IIA and lanthanide (III) metal ions using D-(-)-trans-1,2-cyclohexanediaminetetraacetic acid (D(-)CDTA) as the titrant. A photoelectric polarimeter ...
A study of the cobalt (II) chloride-acetonitrile system by vapor pressure osmometry and visible absorption spectroscopy
(1970)
In recent years, independent investigators have studied the anhydrous system composed of cobalt(II) chloride and acetonitrile and have arrived at results which appear to be somewhat ambiguous. G. J. Janz and co-workers ...
Highly substituted cyclohexanones and bicyclic derivatives: synthesis, structure and NMR studies
(1970)
A new family of 3-aryl-3,5,5-trisubstituted cyclo-hexanones have been synthesized and studied by proton and carbon-13 NMR spectroscopy, [diagram and equation on PDF]. These highly substituted ketones have been prepared by ...
The synthesis of esters, thioesters and selenoesters of dialkylarsinous acids
(1970)
Organoarsenic compounds of the type R₂AsXR' (R=alkyl, R'=alkyl or aryl and X=O, S or Se) have been reported in the literature. The methods described for the synthesis of these compounds involve multistep reactions which ...
Isolation and characterization of nitrogen heterocycle-organolithium reaction intermediates
(1970)
Several intermediates from the reactions of nitrogen heterocycles with organolithium compounds were successfully isolated and were characterized by their proton magnetic resonance (pmr) spectra. Using TMED (N,N,N',N ' ...
Approximate self-consistent molecular orbital theory and calculation of iron enneacarbonyl
(1970)
The development of a pseudo atom model self-consistent field complete neglect of differential overlap (CNDO) molecular orbital theory and localized population analysis methods are described and applied to the iron enneacarbonyl ...
