AB  - This paper reports FT-IR and FT-NIR spectroscopic study of hydrogen bonding between N-mono-substituted caproamides and different ethers (diethyl ether and tetrahydrofuran) in carbon tetrachloride. With increase in ether concentration increase in intensity of red-shifted band, and decrease of intensity of monomer band has been observed. The MIR and NIR spectroscopic characteristics for N-H center dot center dot center dot O hydrogen bonded complexes and also the equilibrium constants for 1:1 complex formation are given. Further, influence of structural differences of ethers on hydrogen bonding was investigated using Taft equation. Good correlation between logarithm of formation constants and Taft steric and inductive factors has been obtained only for tetrahydrofuran in MIR range.

AB  - IR spectroscopic investigation of intramolecular interactions of N-tert-butylformamide (NtBF) in presence of selected ethers as the O-electron donors was carried out. Following ethers were selected based on the different size of sidechain: diethyl ether (DEE), diisopropyl ether (DiPE), methyl-tert-buthyl ether (MtBE), dibutyl ether (DBE), tetrahydrofuran (THF) and tetrahydropyran (THP). Frequency shifts of carbonyl stretching vibration v(C=0) of NtBF in ether solvents were also investigated. The spectroscopic characteristics for N-H center dot center dot center dot O hydrogen bonded complexes are given. Also, the equilibrium constants for 1:1 complex formation in carbon tetrachloride, at 298 K were determined using IR measurements. Further, the wavenumbers of carbonyl stretching vibration v(C=0) were correlated with the Catalan and the linear solvation energy relationships (LSER) solvatochromic parameters.

AB  - Infrared spectroscopy studies of N-methyl benzamide and N-tert-butyl benzamide in 12 organic solvents were undretaken to investigate solvent-solute interactions. The wavenumbers of carbonyl stretching vibration nu(C=O) in different solvents were correlated with the solvent acceptor number (AN), the linear solvation energy relationships (LSER), Catalan solvent parameters (SA, SB and SPP) and Buckingham equation. For both studied amides significant correlation of the position of the carbonyl band with empirical parameters was obtained. Based on obtained results it was assumed that the amide self-association and the steric effects are most important factors that determine position of carbonyl groups band in the IR spectra.

AB  - An attempt was made to investigate the mechanism and kinetics of hydrogen evolution reaction on zinc and platinum wire electrodes from solutions containing ethylene diamine tetraacetic acid (EDTA). EDTA is a tetra-basic acid whose dissociation covers a wide range of pH, with a betaine structure in solutions. Introduction of EDTA into the solution provided several species whose dissociative hydrogen could be a source of h.e.r. The effect of EDTA concentration and pH on the Tafel dependence of cathode process was studied by galvanostatic method and cyclic voltametry. The aim was to establish the effect of EDTA on hydrogen evolution at the electrodes, i.e. whether evolution of hydrogen proceeds via hydronium ions arising from dissociation of EDTA, EDTA anions or hydrogen atoms transferred to the metal from EDTA molecules, as well as the impact of the Rowland effect on h.e.r.
