← ScienceWhich outcome arises when a high-intensity laser interacts with a molecule, exciting electrons to high-lying Rydberg orbitals?
A)Molecular bond dissociation through dipole forces✓
B)Increased vibronic coupling to ground state
C)Enhanced fluorescence with spectral blue-shift
D)Auger electron emission from core ionization
💡 Explanation
When electrons reach high-lying Rydberg orbitals, they create significant electronic polarization because they are far from the core. This polarization generates significant dipole forces leading to molecular bond dissociation. Therefore, bond dissociation results, rather than vibronic coupling, enhanced fluorescence, or Auger emission involving alternate excitation or relaxation paths.
