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 Ca2+ and Al3+ 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.
