Abstract

The g values that have been measured for the group-14 peroxyls are sufficiently similar to suggest that they all have very similar structures. However, the 17O hyperfine splittings seem to indicate that tin peroxyls have structures that differ from their lighter group-14 analogs. We hypothesize that the oxygen atoms in tin peroxyls are magnetically equivalent because they undergo a rapid 1,2-shift. Density-functional and wave-function theory calculations support this view.
