The absorption wavelengths λ_abs (nm) and emission wavelengths λ_em (nm) of molecules H101, CP1 and CP2 together with the Stocks shift at TD-BMK/6-31g(d) levels in dichloromethane solution.

		Absorption				Emission
		λ abs	f	Assignments	λ abs(exp.)a	λ em	Shift (nm)
H101	S0–S1	398	1.81	H → L (92.3%)	400	513	115
CP1	S0–S1	372	2.10	H → L (71.6%)		446	74
CP2	S0–S2	365	1.94	H → L + 1 (54.3%), H → L (7.8%)		437	72
