Abstract

The preference of molecules of the form $H_mX-YH_n$ to adopt hydrogen-shifted structures $H_{m-1}X-Y^+H_{n+1}$ on removal of an electron is theoretically examined. The latter structures are distonic radical cations with the formal charge and radical centres located on different atoms. The relative stabilities of distonic ions relative to classical isomeric forms have been modelled by means of idealized reactions involving small fragments. Ah initis energies for these model reactions indicate the existence of several distonic radical cations more stabilized than currently known systems. Distonic forms are particularly stabilized for the combinations: X = Be, Si, P and S; Y = N, 0 and F.
