Получены интегральные по времени развертки излучения в широком диапазоне спектра 200–675 нм, а также временные осциллограммы излучения кислорода. Анализ полученных панорамных спектров показывает, что при низких скоростях ударной волны в спектре излучения доминирует система молекулярных полос Шумана–Рунге. Повышение скорости ударной волны ведет к появлению в спектре излучения интенсивных атомных линий. Выделены особенности временных осциллограмм для наиболее типичных линий спектра – излучения молекулярного кислорода на длине волны 213 нм (система Шумана–Рунге) и атомарного кислорода на длинах волн 394 и 645 нм.</p></abstract><trans-abstract xml:lang="en"><p>The emission spectra of oxygen behind the front of a strong shock wave have been studied in the shock wave velocity ranges of 5.7–7.4 and 8.1–10.0 km/s at pressures before the wave front of 1.0 and 0.25 Torr. Time-integrated sweeps of radiation in a wide spectral range of 200–675 nm as well as temporal oscillograms of oxygen radiation have been obtained. An analysis of the obtained panoramic spectra shows that at low velocities of the shock wave, the system of Schumann–Runge molecular bands dominates in the emission spectrum. An increase in the shock wave velocity leads to the appearance of intense atomic lines in the emission spectrum. The peculiarities of temporal oscillograms for the most typical spectral lines, such as radiation of molecular oxygen at a wavelength of 213 nm (Schumann–Runge system) and radiation of atomic oxygen at wavelengths of 394 and 645 nm, are highlighted.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ударная волна</kwd><kwd>кислород</kwd><kwd>спектр излучения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>shock wave</kwd><kwd>oxygen</kwd><kwd>radiation spectrum</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского фонда фундаментальных исследований (грант № 20-08-00343).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">G.
