Chlorotriammineplatinum(II) Ion : Acid Hydrolysis and Isotopic Exchange of Chloride Ligand

Description: Abstract: The acid hydrolysis of [Pt(NH3)3Cl] has been shown to occur to a measurable extent. for this reaction: [APt(NH3)cCl]+ + H2O [chemical equilibrium symbol with rate constant k-1 above and k1 below] [Pt(NH3)c(H2O)]++ + Cl-, the equilibrium quotient was measured at 25 degree C and 35 degree C. At 25 degree C this quotient was 8.4 x 10-5 at [Mu] (ionic strength) = 0 and 25 x 10-5 at [mu] = .318 M. This variation is consistent with the expected changes in activity coefficients.

Chemical Binding in the Water Molecule

Description: From Introduction : "This analysis partitions the electron density and the electronic pair density of the molecule into components corresponding promoted atomic states, to quasiclassical coulombic interactions of these promoted states, and to interactions resulting from the sharing of electrons between atoms."

Cation Exchange in Acetone-Water-Hydrochloric Acid

Description: Abstract: Distribution coefficients have been measured for the partition of metal ions between cation exchange resin and acetone-water-hydrochloric acid solutions. the differences in distribution coefficients of metal ions are greater in acetone-water media than in aqueous media of the same hydrochloric acid concentration. Using distribution coefficient data, conditions for column separations of mixtures can be selected. Column separations of metal ion mixtures can be effected by eluting wit… more

Reinvestigation of the CC Stretching and CH3 Rocking Assignments In Isopropyl and tert-Butyl Halides

Description: From report: "In a series of paper (1-3) Sheppard has analyzed the vibrational spectra of simple alkyl halides. During the course of an investigation of the spectra of similar alkyl thiocyanates certain anomalies appeared in the assignments of the CC stretching and methyl rocking vibrations in isopropyl and tert.-butyl halides."

Mass Spectrometric Evidence for the Pyridoxal-Leucine Reaction Mechanism

Description: From Abstract : "The mass spectrum of leucine-dn, prepared by the reaction of pyridoxal with excess leucine in D2O medium, has been established using the crucible source techniques. ... The reaction can be used for the selective α, β-deuteration of amino acids other than leucine.
