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. ...
Just so you know, these rules are going to apply to the rest of organic chemistry. We're going to keep using these rules any time that we're moving electrons, which is pretty much all the time. So what a curved arrow would look like is like this. So notice that I'm...
Answer: The definition of resonance given in the margin says that resonance contributors differ in positions of the electrons but not the nuclei. In this case a pair of electrons that is part of the vertical carbon- oxygen double bond shifts to become a lone pair on the top oxygen. At ...

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...
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 ...
Relaxation- By definition, hyperpolarization is a non-equilibrium phenomenon. This means that as soon as a state of high nuclear spin alignment is created, it starts to relax towards thermal equilibrium. The relevant longitudinalrelaxation timesare typically on the order of seconds to tens of second...
chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures into a resonance hybrid in valence bond theory. definition: resonance structures are sets of lewis structures that describe the ...
While the boundaries of what constitutes “true” microfluidic technology are somewhat difficult to draw, we have used a relatively narrow definition, restricted to systems that not only use small sample volumes, but also exploit at least a small degree of fluidic functionality. For example, ...
