Preferred Label : radiative absorption;
Detailed label : radiative absorption in spectrochemistry;
IUPAC definition : A process by which a particle in the ground state or an excited state may undergo
transition to a higher energy level by absorption of a photon. For a given particle
in the lower state of probability per second of such a transition in a field with
a continuous spectrum is proportional to the spectral radiant energy density of the
absorption line. The proportionality constant is termed the transition probability
for absorption. The transition probability for stimulated emission is defined in a
similar way for the reverse radiative de-excitation process that is induced by the
same radiation field.;
