A general potential usually includes spin-spin interaction, spin-orbit interaction, and tensor force terms.
This instrument enables classroom demonstrations of simple topics, such as free radicals in everyday life, to far less intuitive subjects like electron density, spin-orbit coupling, spin-spin exchange and forbidden transitions.
He covers the role of singular solutions of quantal equations in atomic physics, the classical description of crossings of energy terms and of charge exchange, classical stationary states, understanding the role of the singular spin-spin interaction in the binding energy of two-electron atoms/ions, the last observed line in the spectral series of hydrogen lines in magnetized plasma: s revision of the Inglis-Tellor concept, and extrema in transition energies resulting not in satellites but in dips within spectral lines.
Among the topics are the physical basis of the NMR experiment, proton chemical shifts and spin-spin coupling constants as functions of structure, the influence of molecular symmetry and chirality on proton magnetic resonance spectra, carbon-13 NMR spectroscopy, selected heteronuclei, and NMR of partially oriented molecules and solid-state NMR.
The NMR and one-bond NMR spin-spin coupling constants J(A,B) [75, 76] were computed in Gaussian package using the GIAO method.
Making a breakthrough in the field of particle physics, they have established new limits on what scientists call "long-range spin-spin interactions" between atomic particles.
Spin-spin ([T.sub.2]) and spin-lattice ([T.sub.1]) relaxation times for a variety of grape berries have been reported by Andaur et al.
This also leads and motivates us to study the static and the dynamic spin-spin correlation functions in this model theoretically and compare them with the experimental results from materials which are very good realizations of these models.
To further increase S/N and verify the impact of nuclear spin-spin relaxation rate on spectral shape, the Carr-Purcell-Meiboom-Gill (CPMG) multiecho pulse sequence [16] was applied where all generated echoes in the train were recorded, and coherent summation of selected echoes was done.
Last but not least, in Sivaram's paper [6] on the potential of the strong particle level gravity approach, Sivaram states; "It is seen that the form of the universal spin-spin contact interaction ...
Ela ocorre por meio da relaxacao spin-lattice e da relaxacao spin-spin, as quais sao definidas por duas constantes exponenciais de tempo T1 e T2 respectivamente (THOMSON et al., 1993).
