The i.r. (4000-30 cm^-1) and Raman (4000- 0 cm^-1) spectra of trimethylselenonium iodide and dimethyl selenide have been obtained, together with those of their deuterated analogues.All the active fundamentals of the trimethylselenonium ion have been assigned, assuming C_3v molecular symmetry.Normal coordinate calculations have been carried out for the trimethyl-selenonium ion and dimethyl selenide and the Se-C force constants of both the compounds are compared, including those of other corresponding chalcogenides.
