Spectroscopic measurements of high frequency (hf) plasma were performed under high pressure conditions (5 and 7 MPa) and supercritical (sc) CO $_{2}$ conditions ( MPa). Temperature evaluated from C $_{2}$ Swan bands () increased from 3600 to 4600 K with an increase in pressure. The first observation of broadening and shifting of the O I line profile ( $3{rm s},^5{rm S}_2^o leftarrow 3{rm p},^5{rm P}_{3,2,1}$ ) of hf plasma under sc CO $_{2}$ concisions was carried out. However, the origin of broadening and the shifting cannot be understood because the present theory explaining them is not valid for such high pressure conditions.
