High partial waves for {ital pp} and {ital np} elastic scattering are examined critically from 210 to 800 MeV. Non-one-pion-exchange contributions are compared with predictions from theory. There are some discrepancies, but sufficient agreement that values of the {pi}{ital NN} coupling constants {ital g}{sup 2}{sub 0} for {pi}{sup 0} exchange and {ital g}{sup 2}{sub {ital c}} for charged {pi} exchange can be derived. Results are {ital g}{sup 2}{sub 0}=13.94{plus_minus}0.17{plus_minus}0.07 and {ital g}{sup 2}{sub {ital c}}=13.69{plus_minus}0.15{plus_minus}0.24, where the first error is statistical and the second is an estimate of the systematic error arising from uncertainties in the normalization of total cross sections and {ital d}{sigma}/{ital d}{Omega}.
