Selected properties of organic matter in the humus horizon of soil fertilised with sludge at 10, 20 and 30 Mg ha–1 and with mineral fertilisers (NPK), were examined in the third year after harvesting biomass of Miscanthus sacchariflorus. The following were analysed: TOC, Nt in the soil; the following were analysed in the humic acids isolated from samples – elemental composition, atomic ratios, degree of internal oxidation, absorption coefficient, hydrophilic and hydrophobic properties, IR and 13C NMR spectra (the latter two were used for determination of carbon species). The organic carbon content was found to increase in the pot fertilised with the largest dose of the sludge fertiliser (30 Mg ha–1), while the nitrogen content increased in all the pots fertilised with the organic waste material, as compared with the control pot. Humic acids, isolated from the pots fertilised with sludge and mineral fertilisers (NPK), were found to have a higher degree of internal oxidation. The variance of the other quality parameters of those acids was not significant. Fertilisation with sludge did not significantly affect the properties of humic acids in the third year of cultivation of the test grass, which is important regarding the balance of the soil.

Badano wybrane właściwości materii organicznej poziomu próchnicznego gleby nawożonej osadem ściekowym w dawce 10, 20 i 30 Mg ha–1 oraz mineralnie NPK, w trzecim roku po zbiorze biomasy trawy Miscanthus sacchariflorus. Analizowano: Corg, Nt w glebie, a w wydzielonych kwasach huminowych – skład pierwiastkowy, stosunki atomowe, stopień utlenienia wewnętrznego, wartość współczynnika absorpcji, właściwości hydrofilowo-hydrofobowe, widma w zakresie podczerwieni (IR) oraz 13C NMR i na ich podstawie określono formy węgla. Stwierdzono zwiększenie zawartości węgla związków organicznych na obiekcie nawożonym największą dawką osadu ściekowego (30 Mg ha–1), a azotu na wszystkich obiektach nawożonych tym odpadowym materiałem organicznym, w stosunku do obiektu kontrolnego. Kwasy huminowe materii organicznej wydzielone z gleby obiektów nawożonych osadem ściekowym i mineralnie NPK cechowały się wyższymi wartościami stopnia utlenienia wewnętrznego. Zróżnicowanie pozostałych parametrów jakościowych tych kwasów nie było jednoznaczne. Nawożenie osadem ściekowym nie wpłynęło istotnie na zmianę właściwości kwasów huminowych w trzecim roku uprawy trawy testowej, co jest ważne z punktu widzenia stanu równowagi nawożonej gleby.

Crystals of the Schiff base derivative of gossypol with ethyl 4-amino-1-piperidine carboxylate (GSPC) have been grown and subsequently examined by X-ray diffraction, FT-IR and NMR methods. The crystal space group is P21/n with a = 11.869(1) A, b = 13.540(1) capital A, ring c = 28.119(1) capital A, ring, beta = 91.22(1)° and Z = 4. In the crystal GSPC exists in the enamine-enamine tautomeric form. The intramolecular N(16)–H(16)źźźO(2), N(16’)–H(16’)źźźO(2’) hydrogen bonds assisted by the resonance of the pi-electrons in the aromatic system are the strongest. The FT-IR spectral features of the crystals are in agree - ment with the X-ray data indicating that both parts of the molecule are similarly intramolecular hydrogen-bonded but different intermolecular hydrogen-bonded, al - though the molecule is symmetrically substituted. The FT-IR as well as 1H and 13C NMR spectra have shown that in chloroform solution the enamine-enamine tautomeric form is preserved and the whole structure of GSPC be comes more symmetrical.

A new series of quaternary ammonium tosylates - derivatives of phenyl beta-Dglucopyranoside - has been produced in reactions of phenyl 2,3,4-tri-O-acetyl- 6-O-tosyl-beta-D-glucopyranoside with triethylamine, trimethylamine, 4-(N,Ndimethylamino) pyridine, 2-methylpyridine and pyridine. The structures of the isolates were determined by spectral analysis, including extensive 2D NMR spectral analyses.

1Hand 13CNMRspectra of isoguanine (2-hydroxyadenine) and 8-oxoadenine inH2Oand DMSO-d6 solutions of various acidity have been interpreted using arguments based on the results of several 1D and 2D NMR experiments and theoretical DFT-based calculations. The collected data for H2O solutions can serve for identification of these compounds in body fluids during medical analysis. The 1H and 13C NMR spectra of the investigated compounds in DMSO-d6 solutions have provided information on their tautomeric forms and the mobility of their exchangeable protons.

For three organosodium complexes, diphenylmethylsodium (tmeda) (1), diphenylmethylsodium (pmdta) (2), and fluorenylsodium (tmpda) (3), 13C and 23Na solid state NMR spectra have been measured for the first time. They were analysed in terms of chemical shifts delta(13C) and sigma(23Na) as well as 23Na quadrupole coupling constants, chi(23Na). Due to non-equivalent 23Na atoms in the unit cellMQS-MAS spectra were used to resolve the individual 23Na resonances. The sensitivity of the NMR parameters for the structural features of the complexes is demonstrated.

N,N'-Bis(methyl 3,4,6-tri-O-acetyl-2-deoxy-b-D-glucopyranosid-2-yl)urea 1 and its N'-nitroso derivative 2 were synthesized from methyl 2-amino-3,4,6-tri-O-acetyl-2-deoxy-b-D-glucopyranoside and di(4-nitrophenyl)carbamate. The nitrosation was carried out using N2O3 in dichloromethane. The structure of compounds was analyzed by 1H, 13C, 15N NMR in CDCl3 and 13C CP MAS in the solid state. The assignments of resonances were done by COSY1H, 13C, HETCOR and the 1H, 15N2D correlation spectroscopy. Compound 1 gives one set of 1H/13C resonances in solution, but exhibits polymorphism in the solid state.

The structure and stability of non-linear carbon clusters of carbyne type was estimated based on ab initio quantum mechanical calculations. Both the cyclic (cacarbynes) and knotted (knocarbynes) trefoil structure of closed polycarbon chains, containing up to 84 carbon atoms, were considered. Comparison of the calculated spectral properties (IR, (13)C NMR) with those of C60 fullerene provide the basis for experimental identification of Cn cyclic and knotted structures as may have implication for interstellar dust spectroscopy.
