The Fourier transform (FT)-Raman and infrared (IR) spectra of triphenyl-, perdeuterated triphenyl-, tris(2-methylphenyl)-, tris(3-methylphenyl)-, tris(2,4, 6-trimethylphenyl)-, tris(2-methoxyphenyl)-, tris(3 -methoxyphenyl)-, tris(3-fluorophenyl)- and tris(4-fluorophenyl)-arsine, -stibine and -bismuthine were measured in the range 3600-100 cm(-1). A normal coordinate analysis was performed for all substances using a modified valence force field. This leads to an unique force field for these compounds, where only the metal depending force constants vary noticeably. It was also possible to find a relationship between the chemical nature and the position of the different substituent and the metal-carbon stretching force constant. For all substances H-1-NMR,C-13-NMR and MS data were also given. (C) 1997 Elsevier Science B.V.
