← ScienceWhich mechanism allows electron excitation into antibonding orbitals?
A)Photoinduced charge transfer✓
B)Vibrational energy dissipation
C)Thermally induced structural distortion
D)Solvent molecule rearrangement
💡 Explanation
Photoinduced charge transfer allows electrons to jump into antibonding orbitals because light is absorbed, exciting electrons to higher energy levels, promoting them into unoccupied antibonding orbitals; therefore, charge transfer causes excitation rather than dissipating energy only, leading to structural distortion.
