The stretching-bending bands of ~(13)C_2HD

摘要

The infrared spectrum of ~(13)C_2HD has been investigated using high-resolution Fourier transform infrared spectroscopy. A large number of ro-vibrational transitions in the spectral region 1000-6600 cm~(-1) have been recorded and assigned. This paper is focused only on he vibrational bands involving pure stretching, stretching-bending or stretching-stretching modes. In total, 78 bands have been identified and assigned, 29 related to v_1(CH stretch), 27 to v_2(CC stretch), and 22 to v _3(CD stretch). The data pertaining to each stretching mode have been fitted simultaneously in order to obtain accurate sets of rotational and vibrational parameters for the excited states.
