Показано, что с ростом температуры частотные сдвиги Q-ветвей данных полос увеличиваются в разной степени, при этом относительные интенсивности обертонов 2n2 и 2n4, которые находятся в резонансе Ферми с n1, падают. Предложена методика определения температуры метансодержащих газовых сред. Дана оценка влияния флуктуаций температуры природного газа на результаты измерения его состава методом спектроскопии КР. </p></abstract><trans-abstract xml:lang="en"><p>We investigated the influence of temperature (in the range 20-40 °С) on the main vibrational-rotational bands (ν1, ν2, ν3, 2ν2, and 2ν4) of the methane Raman spectrum. It is demonstrated that if the temperature rises, the Raman shifts of the Q-branches of these bands increases in different ways, and the relative intensities of the 2ν2 and 2ν4, overtones, being in the Fermi resonance with ν1, decreases. A method is proposed for the determination of the temperature of methane-containing gaseous media. An estimation is given for the impact of temperature fluctuations on the results of Raman analysis of the natural gas composition. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>спектроскопия комбинационного рассеяния света</kwd><kwd>метан</kwd><kwd>природный газ</kwd><kwd>температура</kwd><kwd>Raman spectroscopy</kwd><kwd>methane</kwd><kwd>natural gas</kwd><kwd>temperature</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">Д.
