stabilities of three conformational isomers of 2,2′-binaphthalene-1,1′-diol diisobutyrate and the energy barriers to rotation about the pivotal aryl–aryl bond and the two aryl–oxygen bonds were investigated by variable-temperature NMR spectroscopy in conjunction with DFT computations. The experimental and calculated data were found to be in very good agreement and provide new insights into the dynamic
