Variations in the signs and absolute values of <jats:sup>1<\/jats:sup><jats:italic>J<\/jats:italic>(F\uf8ffH), <jats:sup>1<jats:italic>h<\/jats:italic><\/jats:sup><jats:italic>J<\/jats:italic>(H\uf8ffP) and <jats:sup>2<jats:italic>h<\/jats:italic><\/jats:sup><jats:italic>J<\/jats:italic>(F\uf8ffP) have been analyzed and interpreted in terms of changing hydrogen bond type. Of the three phosphorus bases (phosphine, trimethylphosphine and phosphinine) investigated in this study, trimethylphosphine forms the strongest complex with FH, and has the largest two\u2010bond F\uf8ffP coupling constant. Among the relatively simple phosphorus bases, it would appear to be a leading candidate for experimental NMR study. Similarities and differences are noted between the corresponding coupling constants (<jats:italic>J<\/jats:italic>) and the reduced coupling constants (<jats:italic>K<\/jats:italic>) across F\uf8ffH\u2026P and F\uf8ffH\u2026N hydrogen bonds.
