WebSep 6, 2016 · Of all the possible phosphine modes, the tunnelling effect should be most prominent in the symmetric bending mode, ν2, as it is the mode most strongly associated with the height of the pyramid formed with the phosphorous atom on top. In ammonia the analogous ν2 mode is known as the inversion mode. Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and … See more Philippe Gengembre (1764–1838), a student of Lavoisier, first obtained phosphine in 1783 by heating white phosphorus in an aqueous solution of potash (potassium carbonate).
