摘　　要：Two dimensional asynchronous spectra were used to characterize coordination between carbonyl group of butanone and metal ions by using an approach proposed in our recent paper.Spectral variation of n-π^＊transition band of carbonyl group is used to probe the coordination even if metal ions does not possess any characteristic peak in spectra.Experimental results indicate that Ca^2＋ and Al^3＋ show considerable ability to coordinate with the carbonyl group of butanone and bring about spectral variation of the n-π-＊transition band,which is manifested by cross peaks in 2D asynchronous spectra.Two dimensional asynchronous spectra were used to characterize coordination between carbonyl group of butanone and metal ions by using an approach proposed in our recent paper.Spectral variation of n-π^＊transition band of carbonyl group is used to probe the coordination even if metal ions does not possess any characteristic peak in spectra.Experimental results indicate that Ca^2＋ and Al^3＋ show considerable ability to coordinate with the carbonyl group of butanone and bring about spectral variation of the n-π-＊transition band,which is manifested by cross peaks in 2D asynchronous spectra.
