Which orbital outcome occurs when a diatomic molecule absorbs energy?

💡 Explanation

An electron transitions to a higher energy state via photon absorption, increasing antibonding orbital occupancy, because of electron excitation promoting antibonding interactions rather than maintaining bond order or ignoring vibrational effects, therefore favoring molecular instability.
