AB  - Ultraviolet absorption spectra of three isomeric pyridinecarboxylic acids (picolinic, nicotinic, and isonicotinic acids) were measured in 18 various solvents, in the wavelength range from 200 to 400 nm. In order to analyze the solvent effect on the obtained absorption maxima, the ultraviolet absorption frequencies of the electronic transitions in the carbonyl group of the examined acids were correlated using a total solvatochromic equation in the forms nu(max) = nu(0) + s pi(*) + a alpha + b beta and nu(max) = nu(0) + s pi(*) + b beta, where nu(max) is the absorption frequency (1/nu(max)), pi(*) is a measure of the solvent polarity, alpha represents a scale of the solvent hydrogen bond donor acidity, and beta represents a scale of the solvent hydrogen bond acceptor basicity. Correlation of the spectroscopic data was carried out by means of multiple linear regression analysis. The effects of two different solvent types on the ultraviolet absorption maxima of the examined acids were compared and discussed.

AB  - The ultraviolet absorption spectra of the carboxyl group of three isomeric pyridine carboxylic acids N-oxides (picolinic acid N-oxide, nicotinic acid N-oxide and isonicotinic acid N-oxide) were determined in fourteen solvents in the wavelength range from 200 to 400 nm. The position of the absorption maxima (λmax) of the examined acids showed that the ultraviolet absorption maximum wavelengths of picolinic acid N-oxide are the shortest, and those of isonicotinic acid N-oxide acid are the longest. In order to analyze the solvent effect on the obtained absorption spectra, the ultraviolet absorption frequen­cies of the electronic transitions in the carboxylic group of the examined acids were correlated using a total solvatochromic equation of the form Vmax = V0 + + Sπ*+ aα+ bβ, where Vmax is the absorption frequency (1/λmax), π*is a measure of the solvent polarity, β represents the scale of solvent hydrogen bond acceptor basicities and α represents the scale of solvent hydrogen bond donor acidities. The correlation of the spectroscopic data was carried out by means of multiple linear regression analysis. The solvent effects on the ultra­violet absorption maximums of the examined acids were discussed.

AB  - Linear free energy relationships (LFER) were applied to the 1H and 13C NMR chemical shifts in 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)pyridones. The correlation analysis for the substituent-induced chemical shifts (SCS) with inductive (σI), and various resonance (σR) parameters were carried out using SSP (single substituent parameter), DSP (dual substituent parameter), and DSP-NLR (dual substituent parameter non-linear resonance) methods, as well as by multiple regression analysis. The presented calculation accounts satisfactorily for the polar and resonance substituent effects operating at pyridone carbon atoms. Negative ρ values were found for several correlations (reverse substituent effect). The conformations of investigated compounds have been studied by the use of semi-empirical MO-PM6 method and B3LYP density functional (DFT) hybrid methods. The twist of the plane of 4-substituted phenyl ring (θ1) is determined by electronic substituent effects, while the angles θ2 are almost constant.

AB  - The photoelectrochemical properties of a sol-gel prepared titanium oxide coating applied onto a Ti substrate were investigated. The oxide coating was formed from an inorganic sol thermally treated in air at 350°C. The coating consisted of agglomerates of narrow size distribution around 100 nm. The photoelectrochemical characteristics were evaluated by investigating the changes in the open circuit potential, current transients and impedance characteristics of a Ti/TiO2 electrode upon illumination by UV light in H2SO4 solution and in the oxidation of benzyl alcohol. The electrode was found to be active for photoelectrochemical reactions in the investigated solutions.

AB  - The 13C N.M.R. spectra of some substituted α-phenylpyridylacrylic acids, α-phenyl, α-(3-pyrydyl) and α-(3-pyrydyl-N-oxide) cinnamic acids were determined in deuterated dimethyl sulfoxide (d6-DMSO). It has been shown that the subsitutent chemical shifts (SCS) for Cβatom ethylenic bond of the examined compounds correlated linearely with the summ of the corresponding substituent constants in the both rings (σx + σY). This correlation was interpreted as evidence that the electronic effects of both substituents are involved in conjugated aromatic system. © 1992.

It has been shown that the subsitutent chemical shifts (SCS) for Cβatom ethylenic bond of the examined compounds correlated linearely with the summ of the corresponding substituent constants in the both rings (σx + σY). This correlation was interpreted as evidence that the electronic effects of both substituents are involved in conjugated aromatic system. © 1992.",

AB  - 13C n.m.r. spectra of some 5-substituted-3-isopropyl-6-methyl uracils were determined in deuterated dimethyl sulfoxide (d6 - DMSO). The substituents are : H, Cl, Br, J, NO2, NH2, N(CH3)2, C6H5, C6H4-NO2-p and C6H4-NH2-p. It has been shown that 13C chemical shifts of C-5 of some of the examined compounds correlated linearly with the 13C chemical shifts of C-5 in the 5-substituted uracils as well as with the 13C chemical shifts of the substituted carbon in an analogues series of monosubstituted benzenes. The 13C chemical shifts of C-6 in some of the above compounds depend on the steric effects of the substituent in position 5 of the uracil ring. © 1990.
