Path I : The molecule may lose rest of the energy also in the
form of heat so that the complete path is non-radiative or
radiation less transitions.
Path II: Molecule releases energy in the form of light or uv
radiation. This is called Fluorescence
Path III : Some energy may be lost in transfer from S1 to T1 in
the form of heat. It is called intersystem crossing (ISC).
This process involves transition between states of different
spins (parallel to antiparallel), ie, different multiplicity.
This path is non-radiative.
Path IV : After ISC, the molecule may lose energy in the
form of light in going from the excited triplet state to the
ground state. This is called phosphorescence.
