Дослiджено неполяризованi спектри раманiвського розсiювання свiтла монокристалiв TlIn(S0,95Se0,05)2 в дiапазонi частот 16–340 cm−1 в температурному iнтервалi 30 K ≤ T ≤ 293 K. Проведено апроксимацiю експериментальних спектрiв суперпозицiєю лоренцових контурiв i визначено температурнi залежностi напiвширин, iнтенсивностей та частот оптичних мод. Показано, що деякi особливостi температурних залежностей пов’язанi з iснуванням фазових переходiв у дослiджуваних об’єктах.
