Table 2. Data (in eV and in kcal mol^–1 within Parentheses) to Assess the Ability of OG and G to Photoinduce the CPD Ring Opening, Experimental Absorption Band Origin (E_S*), Computed AIP, Calculated Energy Change (ΔE_red)*, Related to the Photoreduction (OG*/G* + CPD → OG^•+/G^•+ + CPD^•–), and Energy Barrier (ΔE_pc^⧧) for the Overall Process OG*/G* to the CPD Split Product (See the Text)^a.

	ES* (exp)	AIP(D)	(ΔEred)*	ΔEpc⧧
OG	3.90 (90.0)	5.48	–0.84 (−19.4)	–0.74 (−17.1)
G	4.10 (94.6)	5.78	–0.75 (−17.2)	–0.65 (−14.9)
