A phenomenon exhibited by an alternating-current circuit in which there are relatively large currents near certain frequencies, and a relatively unimpeded oscillation of energy from a potential to a kinetic form; a special case of the physics definition. ...
The text by Atkins and Symons integrates spin resonance and quantum chemistry.205 The definition and determination of spin density via EMR hyperfine coupling measurements naturally follows from the Fermi treatment of the nuclear hyperfine interaction in which the electron density explicitly appears.204–...
Dewar's recent definition of resonance energy (1) for hydrocarbons is extended to molecules containing oxygen, and resonance energy values are calculated from experimental heats of formation for a variety of conjugated organic compounds. A simple additivity scheme is proposed whereby resonance energies ...
However, all three concepts lack a real space definition, that is not reliant on orbitals or specific wave function expansions. Here, we outline a redefinition from first principles: delocalization means that likely electron arrangements are connected via paths of high probability density in the many...
excellent definition of internal side chains is illustrated inFig. 8C. Because of the high resolution of the interleukin-1β structure, it was possible to analyze in detail side-chain–side-chaininteractions involved in stabilizing the structure. In addition, examination of the structure in the ...

Time-Resolved Electron Paramagnetic Resonance In subject area: Chemistry Time-Resolved Electron Paramagnetic Resonance is a technique that involves studying the behavior of paramagnetic species over time using spectroscopic methods. AI generated definition based on: Spin Resonance Spectroscopy, 2018 ...
NMR spectroscopy is a technique exploiting the magnetic properties of specific atomic nuclei. It is based on the phenomenon of nuclear magnetic resonance (NMR). The most important applications for organic chemistry are proton and carbon-13 NMR performed in liquid solutions. But NMR is also applicabl...
