✦ Synopsis

lBF and 31P decoupling experiments are used to simplify the proton spectra of paraand 4J(31P . . . H) are positive, and 5J(31P . . . l9F) is negative in the trivalent phosphorus derivatives, and all become more positive as the valency of the phosphorus atom is increased. A triple resonance experiment is used to show that 7J(s1P. . * H) in [p-CHsC6H4CH,P@(C8HS)3] is negative. The double resonance technique is used to relate the slP chemical shifts to the tetramethylsilane resonant frequency. substituted derivatives of triphenyl phosphine, prior to lH-{'H} tickling experiments. 3J(31P . . .
