An electrostatic interaction model applied to complexes of sulfur dioxide

The Buckingham-Fowler electrostatic model has been applied to a number of known weakly bound complexes of SO2 with the objective of predicting the geometries of these complexes. In most of the cases investigated, this relatively simple model has reproduced many features of the angular geometries of the complexes remarkably well, even in cases where the experimental structures were found to be very asymmetric in nature. However, for the butadiene and furan complexes with SO2, the predicted geometries did not resemble the experimental determinations, despite numerous attempts to produce these structures.
