← ScienceWhich outcome occurs when an organic molecule's excitation surpasses photostability limits?
A)Molecular photodissocation and bond breaking✓
B)Increased solvation energy by local environment
C)Enhanced fluorescence quantum yield
D)Increased nuclear localization signal expression
💡 Explanation
Molecular photodissociation occurs because surpassing photostability results in bond weakening, leading to bond breakage via homolytic or heterolytic cleavage. Therefore, molecular photodissociation occurs, rather than alternative processes like increased solvation, under conditions exceeding photostability limits.
