Разработанный метод существенно увеличивает возможности детектирования слабых линий КР благодаря пакетной обработке набора экспериментальных спектров ВКР-ХГ, позволяющей оптимизировать процессы разложения этих спектров и усреднения полученных из них колебательных спектров. Метод апробирован на спектрах ВКР-ХГ лазерного красителя пирометена 597 в везикулярной пленке. Полученные результаты хорошо согласуются со спектром КР, рассчитанным методом Хартри-Фока.</p></abstract><trans-abstract xml:lang="en"><p>An iterative method is developed to obtain the vibrational spectrum of laser organic dyes from the spectra of their secondary radiation which manifests itself in multiply scattering media as a coupled process of chaotic generation (CG) and stimulated Raman scattering (SRS). The developed method significantly increases the detection capabilities of weak Raman lines due to the batch processing of a set of experimental SRS-CG spectra, which makes it possible to optimize decomposition of these spectra and averaging of the vibrational spectra obtained from the set of experimental SRS-CG spectra. The method was tested on the spectra of an SRS-CG laser dye of pyromete 597 in a vesicular film. The results obtained are in good agreement with the Raman spectra calculated by the Hartree-Fock method. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>хаотическая генерация</kwd><kwd>вынужденное комбинационное рассеяние (ВКР)</kwd><kwd>органические красители</kwd><kwd>многократно рассеивающая среда</kwd><kwd>колебательный спектр</kwd><kwd>итеративный метод</kwd><kwd>пирометен 597</kwd><kwd>random lasing</kwd><kwd>stimulated Raman scattering</kwd><kwd>organic dyes</kwd><kwd>multiple scattering media</kwd><kwd>vibrational spectrum</kwd><kwd>iterative method</kwd><kwd>pyrromethen pm597</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zhou Zeng-Hui, Liu Li, Wang Gui-Ying, Xu Zhi-Zhan.
