Abstract

The high–resolution Fourier–transform spectrum of C2D4 was recorded at the optical resolution of up to 0.00096 cm−1 and analyzed in the region of 460–710 cm−1, where the whole ν10 band was considered including P, Q and R branches. The experimentally recorded line positions (5040 experimental lines with Jmax.=47 and Ka max.=27) are theoretically analyzed, and effective spectroscopic parameters are derived from the corresponding fit procedures. The 1247 ro–vibrational energies of the (v10=1) vibrational state are reproduced by a set of 47 fitted spectroscopic parameters with the drms=2.2×10−4 cm−1. Line list of the ro–vibrational transitions of the ν10 band is presented in the Supplementary material.
