Question:
When a transition between states of the same multiplicity occurs without emitting light, the process is called:
When a transition between states of the same multiplicity occurs without emitting light, the process is called:
Show Hint
Compare fluorescence, internal conversion, intersystem crossing and quenching by radiative nature and multiplicity change.
Updated On: Jul 3, 2026
- Fluorescence
- Internal conversion
- Quenching
- Intersystem crossing
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Fluorescence: radiative, same multiplicity.
Step 2: Internal conversion: non-radiative, same multiplicity.
Step 3: Intersystem crossing: non-radiative, different multiplicity. Quenching: external collision.
\[\boxed{\text{Internal conversion}}\]Was this answer helpful?
