Abstract
The signs and magnitudes of 3J(31P 1H), 3J(31P 19F), and other coupling constants have been determined by multiple-resonance methods in methyl and trifluromethyl derivatives of platinum(II), platinum (IV), gold(I), and gold (III). Whilst 3J(31P 1H) is more negative when the coupling path is trans than when it is cis, the converse is true of 3J(31P 19F). The coupling fall into ranges which are sufficiently distinct to permit their diagonistic use, and their origin is discussed in terms of the bonding in the complexes.Keywords
