在高压条件（5和7 MPa）和超临界（sc）CO2条件（8-20 MPa）下进行高频（hf）等离子体的光谱测量。从C-2天鹅带（d（3）Pi（g）-> a（3）Pi（u））评估的温度随着压力的增加从3600 K增加到4600 K。首次观测到了超临界CO_2条件下hf等离子体氧碘谱线轮廓（3 p（5）P-3，P-2，P-1 -> 3s（5）S-2（0））的展宽和移动。然而，加宽和移动的起源不能被理解，因为目前解释它们的理论对于这样的高压条件是无效的。
Spectroscopic measurements of high frequency (hf) plasma were performed under high pressure conditions (5 and 7 MPa) and supercritical (sc) CO2 conditions (8-20 MPa). Temperature evaluated from C-2 Swan bands (d (3)Pi(g)-> a (3)Pi(u)) increased from 3600 to 4600 K with an increase in pressure. The first observation of broadening and shifting of the O I line profile (3p (5) P-3,P-2,P-1 -> 3s (5) S-2(0)) of hf plasma under sc CO2 conditions 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.
