← ScienceWhich consequence results when quenching molecular orbitals in photochemistry?
A)Increased fluorescence quantum yield
B)Suppressed intersystem crossing events
C)Reduced phosphorescence intensity✓
D)Enhanced singlet oxygen production
💡 Explanation
Quenching deactivates the excited triplet state using energy transfer; therefore, phosphorescence output must be reduced via radiationless decay, because triplet state population decreases significantly, rather than alternatives like enhanced fluorescence.
