Answer:
Internal conversion is the radiationless transition between energy states of the same spin state (compare with fluorescence-a radiative process). Intersystem crossing is a radiationless transition between different spin states (compare to phosphorescence).
Intersystem crossing is another process where fluorescence signal is reduced and phosphorescence is generated. ... Intersystem crossing describes the relaxation of the molecule from a singlet excited state to a lower energy, triplet excitation state.
This is termed fluorescence. It is indicated on a Jablonski diagram as a straight line going down on the energy axis between electronic states. ... This difference is because energy is lost in internal conversion and vibrational relaxation, where it is transferred away from the electron.
