This report contains a method for determining the van der Waals and acid-base contributions to the overall {sup 31}P chemical shifts ({Delta}{delta}{sup d} and {Delta}{delta}{sup ab}) and to the Acceptor Numbers (AN{sup d} and AN{sup ab}) of the Meyer and Gutmann two-component systems, and to illustrate the method with experimental results for thirty-two liquids. 9 refs., 9 figs., 6 tabs.
