The results of various 15 N solid-state NMR experiments performed on solid samples of doubly 15 N-labeled 3,5-dimethylpyrazole, 5-methyl-3-phenylpyrazole, (PMP), and 3,5-diphenylpyrazole are reported. In the solid state, these compounds form various

The sensitivity of one-dimensional dynamic magic-angle spinning (MAS) and off-MAS 2 H nuclear magnetic resonance spectra to changes in the parameters of jump-type molecular motions is studied. The Floquet theory approach is used to simulate spectra o

Two routes for the exploitation of the t-SEDRA pulse scheme, which induces coherence transfer in dipolar-coupled homonuclear spin systems in rotating samples, are demonstrated and discussed. This sequence is utilized to deduce intramolecular connecti

The effective Hamiltonian of the "simple excitation for the dephasing of the rotational-echo amplitudes" (SEDRA) experiment has been derived. This experiment enables the determination of the strength of the dipolar interaction of a homonuclear spin p

The entropy of reaction is incorporated in a classical model by introducing frequency changes in the harmonic modes. Various properties, such as the rate constant dependence on the energy of reaction and on the temperature, are influenced by the numb

Magic-angle-spinning (MAS) NMR experiments can be described in terms of Floquet theory. In this publication the Floquet approach is formulated in terms of Floquet density matrices and Floquet evolution operators. Expressions for expectation values of

The use of recycled water for irrigation purposes in agriculture is probably the most effective response to the scarcity of water resources in Israel. Base-line studies of the quality of recycled irrigation water in the Beith Alpha basin (more than 1
