Исследование фундаментальных полос nu12 в молекулах C2H4 и C2H2D2-cis

Abstract

В данной работе были проанализированы инфракрасные спектры молекул C2H4 и C2H2D2-цис. В результате анализа спектров молекулы C2H4 в области полосы v12, было получено 998 интенсивностей линий. Было проинтерпретировано порядка 5600 переходов, принадлежащих полосам v12(B1), v3(A1), 2v10(A1) и v8+v10(A2) молекулы C2H2D2-цис.

In this work, the high-resolution infrared spectra of C2H4 were analyzed in the region of 1360 –1530 cm^?1 , where the strong ?12 band is located. 998 line strengths (1491 transitions) were determined from the fit of their line shapes with a Hartmann–Tran profile. High–resolution infrared spectra of the C2H2D2?cis molecule were analyzed in the region of 1150 – 1450 cm^?1, where the strongly interacting ?12(B1), ?3(A1), 2?10(A1) and ?8 + ?10(A2) bands are located. For these four bands 5594 transitions with maximum values of quantum numbers Jmax = 50 and Kmax a = 21 were assigned.
