文摘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.
