← ScienceWhich energetic consequence results in UV induced photobleaching?
A)Electronic configuration of excited state decays✓
B)Vibrational relaxation causes fluorescence
C)Increased collisional quenching occurs rapidly
D)Singlet oxygen production increases drastically
💡 Explanation
Photobleaching follows when light causes electronic excitation, promoting electrons to higher molecular orbitals; de-excitation via bond breakage follows rather than typical fluorescence because the high energy causes a destabilization, therefore structure degradation occurs.
