Table 1. UV–Visible Spectral (Electronic) Information of the (Acetonedicarboxylato)copper Solution^a.

wavelength (nm)	molar absorbance (M^–1 cm^–1)
242	N.D.^b	π → π*	H₂Acdica_(enol)^1– and [Cu^II(H₂Acdica)_enol]¹⁺
246	6970	π → π*	[Cu^II(HAcdica)_enol]⁰
400	151^c	2p → d	(O)π → Cu^II
757	60.7^c	d–d	[Cu^II(HAcdica)_enol]⁰

Note: 246 nm data were obtained at pH 7.25 from Figure 2a.

This molar absorbance was not determined because the species may be a mixture.

This data was obtained from Figure S4 at pH 7.00.
