Обработка спектроскопических данных выполнена как в рамках классического подхода «peak fitting», так и при использовании статистических подходов. Высказано предположение, что при повышении температуры трансформация тетраэдров MoO4 и WO4 в пространстве неодинакова, для Ca-содержащих соединений объем элементарной ячейки при повышении температуры увеличивается медленнее, чем объем полиэдра WO4 (MoO4). Подобное различие определяется тепловым расширением, контролируемым преимущественно расширением полиэдров CaO8 (SrO8).</p></abstract><trans-abstract xml:lang="en"><p>Here we present the results from an in situ Raman thermal spectroscopy study on specific features of the lattice dynamics of scheelite-type compounds (natural and synthetic scheelite, synthetic CaMoO4 and SrMoO4) in the temperature range of 83–873 K. Spectroscopic data processing has been carried out based on both classical "peak fitting" and statistical approaches. It has been suggested that an increase in temperature causes nonuniformity of MoO4 and WO4 tetrahedra transformation. It has been assumed that dynamics in thermal expansion of unit cells of Ca-containing compounds is slower than that in thermal expansion of WO4 (MoO4) polyhedral. This diffence is mainly due to the fact that thermal expansion is mainly defined by the expansion of CaO8 (SrO8) polyhedra.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>шеелит</kwd><kwd>повеллит</kwd><kwd>комбинационное рассеяние</kwd><kwd>тетраэдр</kwd><kwd>статистические параметры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scheelite</kwd><kwd>powellite</kwd><kwd>Raman scattering</kwd><kwd>tetrahedron</kwd><kwd>statistical parameters</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в ЦКП УрО РАН «Геоаналитик» в рамках темы № АААА-А18-118053090045-8 государственного задания ИГГ УрО РАН (КР спектроскопия и РСМА – 50 %), гранта РНФ № 20-73-10048 (синтез и аттестация образцов – 50 %).
