The intermolecular hydrogen bond and proton transfer of the system, acetic acid -pyridine was investigated by means of the semi-empirical PCILO (Perturbative Configuration Interaction using Localised Orbitals) method. A potential curve with a single minimum was found in the 1:l complex of acetic ac
The semi-empirical PCILO (Perturbative Configuration Interaction using Localized Orbitals) method has been used to study intermolecular hydrogen bonding and proton transfer in the acetic acid -imidazole system. The effect of specific hydration on the proton potential functions was investigated (with
The kinetics of the isotope exchange reactions of RCH(COOH) 2 (R"H, D, Me, Et, Bu, and Ph) in D 2 O solution were studied by using 1 H NMR spectroscopy. It was observed that the rate of isotope exchange reaction was inhibited by the presence of 1 M of DNO 3 , DCl, DBr or D 2 SO 4 and catalyzed by th
Splittings, 6,, were observed for each carbon atom, C,, of chalcone in spectra obtained from coaxial 5 and 10 mm NMR sample tubes containing solutions equimolar in the concentration of the ketone and of TFA or TFA-d as hydrogen-bond donors, respectively. It was found that a linear expression, S,A,+x
