1,3-Shifts in [(η6-C8H8)Cr(CO)3]. Application of the Forsén–Hoffman spin saturation method to a four-site 13C nuclear magnetic resonance problem
Abstract
[(η6-C8H8)Cr(CO)3] has been shown to be fluxional by means of 1,3- and, to a lesser extent, 1,2-shifts; this work clearly proves the earlier suggestion of random shifts to be wrong.
