It is shown that conjugation in the phosphines produces an intensification of Raman bands and a simultaneous bathochromic shift of the electronic absorption spectra for all the phosphines, except of phenylphosphine PhPH2, where the lone pair on PIII does not conjugate with phenyl moiety. Nevertheless, the lone pair is able to conjugation within more expanded aromatic π-systems, and the conjugational effects are strongly enhanced as π-system of arylphosphines expands.
