21. 20 Known increments of the phosphine were weighed out on a microbalance in the glovebox and added to known amounts of THF and indicator. The mixture was allowed to reach equilibrium, and the spectrum was taken. Alternatively, known increments of THF were added to known solutions of phosphine and indicator. The experimental results are tabulated in Table S1 (Supporting Information).
