← ScienceFor a molecule absorbing a photon of specific energy, which mechanism causes electrons to transition between orbitals?
A)Quantum confinement shifting the bandgap
B)Resonant frequency inducing electron excitation✓
C)Intersystem crossing altering spin multiplicity
D)Franck-Condon principle enabling nuclear motion
💡 Explanation
When a molecule absorbs a photon matching the energy difference between two orbitals, resonant frequency induces electron excitation because the photon's electromagnetic field coherently drives the electron to a higher energy state. Therefore resonant excitation results, rather than confinement, intersystem crossing or nuclear motion which depend respectively on spatial constrain, spin changes or nuclear dynamics.
