A mathematical analysis of the governing equations of triply diffusive fluid layer with one of the components as heat with diffusivity κ, prescribes upper limit for the complex growth rate of oscillatory motions of neutral or growing amplitude in such a manner that it naturally culminates in sufficient conditions precluding the non- existence of such motions. Further, the results derived herein are uniformly valid for quite general nature of bounding surfaces.
