It might be unexpected that the Karplus equation, which was first derived for 3JHH coupling constants, should also apply to three-bond coupling between the nuclei of metallic elements such as tin. T.N. Mitchell and B. Kowall (Magn. Reson. Chem. 33, 325 (1995)) have studied the relation between 3JHH and 3JSnSn in compounds of the type Me3SnCH2CHRSnMe3 and find that 3JSnSn = 78.86 Hz and 3JHH =27.84 Hz. (a) Does this result support a Karplus type equation for tin nuclei? Explain your reasoning. (b) Obtain the Karplus equation for 3JSnSn and plot it as a function of the dihedral angle. (c) Draw the preferred conformation.
