The direction of the calculated IR and NMR peak shifts for dimer formation is consistent with our experimental data. For a general reference about the B3LYP/6-31G* calculation see: Foresman, J. B.; Frisch, A. Exploring Chemistry with Electronic Structure Methods, 2nd ed.; Gaussian, Inc.: Pittsburgh, 1996. We thank Professor Frank Weinhold for performing this calculation.
