Question:easy

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.

  • Fluorescence
  • Internal conversion
  • Quenching
  • Intersystem crossing
Show Solution

The Correct Option is B

Solution and Explanation

Classification table: only internal conversion satisfies both same multiplicity AND no light emitted.
\[\boxed{\text{Internal conversion}}\]
