Preferred Label : radiative transition;
IUPAC definition : A transition between two states of a molecular entity, the energy difference being
emitted or absorbed as photons. In principle, radiative and radiationless transitions
can be distinguished in molecules. The first occur by absorption or emission of light
quanta, and the latter is the result of the transformation of electronic excitation
energy into vibrational/rotational energy.;
