Preferred Label : energy transfer;
Detailed label : energy transfer in photochemistry;
IUPAC definition : From a phenomenological point of view, the term is used to describe the process by
which a molecular entity absorbs light and a phenomenon originates from the excited
state of another molecular entity. In mechanistic photochemistry the term has been
reserved for the photophysical process in which an excited state of one molecular
entity (the donor) is deactivated to a lower-lying state by transferring energy to
a second molecular entity (the acceptor) which is thereby raised to a higher energy
state. The excitation may be electronic, vibrational, rotational or translational.
The donor and acceptor may be two parts of the same molecular entity, in which case
the process is called intramolecular energy transfer.;
