【 摘 要 】

Study of deuterated isotopologues is significant for the expansion of information quantity about "mother" modification of molecule. The spectra of cis-ethylene-d2 (C2H2D2-cis) and ethylene-d3 (C2HD3) molecules have been recorded with a Bruker IFS 120 HR Fourier spectrometer in the region of the ν3 bands location with spectral resolution of 0.0021 cm-1. As a result of the experimental spectrum analysis, more than 1200 and 1000 transitions have been assigned for the ν3 bands of C2H2D2-cis and C2HD3, respectively. Study of these bands for both investigated molecules was made at first time.
