← ScienceWhich outcome occurs when chromophores absorb intense light?
A)Excited-state molecular distortion and bond vibrations✓
B)Rapid equilibration prevents photochemical reactivity
C)Increased solvent reorganization stabilizes ground state
D)Fluorescence quenching accelerates radiative decay pathway
💡 Explanation
Intense light absorption promotes electrons to higher energy levels, causing excited-state molecular distortion through the Franck-Condon principle; therefore, molecular geometry changes result, rather than immediate relaxation, because bond vibrations redistribute energy.
