    The potential energy consts. of H2SO4 and H2SeO4 were obtained by the method of characteristic set of valence coordinates. The vibrational mean amplitudes for the various characteristic bonds, including the nonbonded distances and Coriolis coupling consts. were evaluated

    In this paper the details of an indegenously developed automated High Pressure Oxidation System (HiPOS) are presented. This system is completely computer controlled and is capable of thermal oxidation/ nitridation and annealing at pressures upto 10 Bar and temperatures in the range 200 - 1000°C. The paper includes the experimental results obtained on the dry oxidation of silicon at 900°C at pressures in the range 1 to 10 atmospheres
