Farklı organik gübrelerin ve kombinasyonlarının adaçayı (Salvia fructicosa Mill.) bitkisinde besin içeriğine ve uçucu yağ miktarına etkisinin incelendiği bu çalışmada sığır gübresi, koyun gübresi ve tavuk gübresi kullanılmıştır. Yetiştiricilik sonunda N, P, K, Mg, Fe, Zn, Mn, Cu ve uçucu yağ içerikleri belirlenmiş ve değerlendirilmiştir. Bitkilerin besin elementleri içeriklerine organik gübre uygulamaları farklı etkilerde bulunurken uygulamaların etkisi istatistiksel olarak % 1 düzeyde önemli bulunmuştur. Uçucu yağ içerikleri organik gübre uygulamalarıyla artmış ve en fazla uçucu yağ % 2.9 ile tavuk gübresi - koyun gübresi karışımdan elde edilmiştir. Sonuç olarak tıbbi-aromatik bir bitki olan adaçayı bitkisinde besin maddesi miktarları ve uçucu yağ içerikleri organik gübre uygulamalarıyla artmış ve bitki gelişimine olumlu etkilerde bulunmuştur

WOS: 000089278600009 The Electron Paramagnetic Resonance spectra of Cu2+ in CdCa (CH3COO)(4) . 6H(2)O (cadmium calcium tetraacetate hexahydrate) powder and single crystal have been recorded at 300 and 133 K. The angular variation of the spectra indicated the substitution of the host Cd2+ with Cu2+. The observed values of the g and A hyperfine tensors were found to be temperature dependent, and this dependence is discussed and explained on the basis of dynamic Jahn-Teller effects. The spin-Hamiltonian parameters were found to be axial symmetric at room temperature, whereas they showed deviations from axial symmetry at low temperature. The g and A tensors where found to be coaxial within the limits of experimental errors, and the ground state wave functions of the complex at 300 and 133 K have been constructed.

Electron Paramagnetic Resonance spectra of Cu2+ doped into cadmium barium formate dihydrate single crystal were studied at 300 K. The powder spectrum of this material was studied at 300 to 133 K. The values of the g and A hyperfine tensors were found to be temperature dependent. The temperature dependence of the Cu2+ EPR spectrum is discussed in terms of the dynamic Jahn-Teller effect. The angular variation of the spectra indicates the substitution of the host Cd2+ with Cu2+. The spectra were fitted with a tetragonal spin-Hamiltonian, the parameters of which were determined at 300 K. The ground-state wave function of the copper complex has been constructed at 113 K and 300 K.

WOS: 000072138300029 A detailed study of VO2+ in tetragonal mixed crystals Ca(HCOO)(2)-Sr(HCOO)(2) has been carried out at room temperature. Impurity sites in the unit, cell and the molecular structure of the vanadyl complexes in the crystal are discussed. The spin-Hamiltonian parameters have been calculated from single crystal as well as the powder spectra. The g and A tensors are found to be axially symmetric. Correlating the optical and EPR data the molecular orbital coefficients and crystal-field parameters are calculated and discussed.

WOS: 000071958400003 The results of an electron paramagnetic resonance (EPR) study of vanadyl ion VO2+ doped in single crystals of Ba (ClO4)(2) . 3H(2)O are reported. The spectra indicated the presence of two substitutional and interstitial sites depending on the orientation. The spin-Hamiltonian parameters were determined from single crystal and powder EPR data. These parameters were found to be axial symmetric for the powder sample, whereas they showed deviations from axial symmetry for the single crystal.
