At the same time, no signs of hydrocarbons or other organic compounds were found, what excludes contamination of the sample at the preparation stage and the effect of the adhesive layer of the scotch on which the regolith fragments under study were mounted, and also contamination of the sample by the exhaust of hydrazine landing engines of the descent capsule of the AS “Luna-24”.</p></abstract><trans-abstract xml:lang="ru"><p>При изучении образцов лунного реголита из проб АС “Луна‑24” с использованием методов рамановской спектроскопии установлено наличие трёх структурных модификаций углерода: аморфного <italic>sp</italic><sup>2</sup>-углерода, шунгитоподобного углерода и турбостратного графита. Но при этом также не обнаружено признаков углеводородов и других органических соединений, что исключает загрязнение пробы на этапе подготовки и влияние клеящего слоя скотча, на котором были размещены изучаемые фрагменты реголита, и также загрязнение пробы выхлопом гидразиновых двигателей посадки спускаемого аппарата АС “Луна‑24”.</p></trans-abstract><kwd-group xml:lang="en"><kwd>lunar regolith</kwd><kwd>moon minerals</kwd><kwd>carbon</kwd><kwd>molybdenum</kwd><kwd>Raman spectroscopy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лунный реголит</kwd><kwd>минералы Луны</kwd><kwd>углерод</kwd><kwd>молибден</kwd><kwd>рамановская спектроскопия</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Research Work</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Научно-исследовательская работа</institution></institution-wrap></funding-source><award-id></award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Мохов А. В., Карташов П. М., Богатиков О. А., Магазина Л. О., Ашихмина Н. А., Копорулина Е. В.
