Which consequence results when excessive vibrational excitation occurs in molecular iodine?

💡 Explanation

Excessive vibrational excitation increases the potential energy, favouring bond cleavage via photochemical decay; because this mechanism lowers the threshold needed to break the relatively weak I-I bond, therefore photochemical decay pathways emerge, rather than molecular stabilization.
