← ScienceWhich behavior arises under intense electromagnetic radiation interacting with molecular iodine?
A)Bond dissociation via electronic excitation✓
B)Increased vibrational mode anharmonicity
C)Enhanced rotational state degeneracy
D)Decreased ionization energy threshold
💡 Explanation
Intense electromagnetic radiation causes bond dissociation via electronic excitation because photons promote electrons, weakening the molecular bonds. Therefore, the molecule breaks apart rather than exhibiting vibrational changes or rotational degeneracy, which require less energy.
