摘要：

Application of Hoffmann's Extended Hückel MO method to diazoacetone and α-diazoacetophenone has been found to provide a quantum mechanical basis for previous postulations that α-diazo ketones can exist in two conformations. These are shown to be the cis and trans conformers for both diazoacetone and α-diazoacetophenone. It has been shown also that the electronic spectra of these α-diazo ketones, when resolved into Gaussian components, can be satisfactorily interpreted in terms of the energy levels calculated for each pair of conformers. © 1969.
