Physical organic chemistry

epimerization

Chemistry; Physical organic chemistry

Interconversion of epimers by reversal of the configuration at one of the "stereogenic" centers.

excimer

Chemistry; Physical organic chemistry

An excited dimer, "non-bonding" in the ground state. For example, a complex formed by the interaction of an excited molecular entity with a ground state counterpart of this entity.

exciplex

Chemistry; Physical organic chemistry

An electronically excited complex of definite stoichiometry, "non-bonding" in the ground state. For example, a complex formed by the interaction of an excited molecular entity with a ground state ...

excited state

Chemistry; Physical organic chemistry

State of a system with energy higher than that of the ground state. This term is most commonly used to characterize a molecule in one of its electronically excited states, but can also refer to ...

extended Hammett equation

Chemistry; Physical organic chemistry

This term applies in a general way to any multiparametric extension of the Hammett equation. It is sometimes used specifically for a form of dual substituent-parameter equation in which the actual ...

fast-atom bombardment (FAB) mass spectroscopy

Chemistry; Physical organic chemistry

A method in which ions are produced in a mass spectrometer from nonvolatile or thermally fragile organic molecules by bombarding the compound in the condensed phase with energy-rich neutral ...

field effect

Chemistry; Physical organic chemistry

An experimentally observable effect symbolized by F (on reaction rates, etc.) of intramolecular coulombic interaction between the center of interest and a remote unipole or dipole, by direct action ...
