High Concentrations

It has been claimed by Enderby and co-workers that changes in long-range order occur in NiCl2 aqueous solutions at high concentrations. To investigate the possibility of a transition, the partial molar heat capacities and volumes of NiCl2, CaCl2, MgCl2, and NaCl were measured and compared in water at 25 °C up to 6 mol kg−1. In the case of NaCl, data were also measured at 5 and 45 °C. A slight change in slope of [Formula: see text] is observed for NiCl2 around 4 mol kg−1 which may suggest a third or higher order transition. However, the change is too small to support unambiguously any particular model for the high concentration region.

Spin Spin Coupling

On the basis of N.M.R. spectra, supported by u.v. and i.r. data, it can be concluded that "p-nitrosophenol" and several of its methyl derivatives exist predominantly in the benzoquinone monoxime form in organic solvents and that in aqueous solutions the corresponding potassium salts have the negative charge largely on the oxime oxygen. The protons on the α-carbon syn to the quinone monoxime hydroxyl are deshielded with respect to the anti protons but this relationship appears to be reversed in the anions. The N.M.R. spectra of some p-nitrosoanisoles and quinone monoxime methyl ethers are given and syn-anti equilibria and long-range spin-spin coupling are discussed.
