The number of defined events which occur per
photon absorbed by the system. The integral quantum yield is:
For a
photochemical reaction:
The differential quantum yield is:
where
is the rate of change of a
measurable quantity, and
the amount of photons (mol or its equivalent
einstein) absorbed per unit time.
can be used for
photophysical processes or photochemical reactions.
