Abstract
The high–resolution infrared spectrum of C2H2D2-cis was recorded for the first time and analyzed in the region of 2400–2700 cm−1, where the ν2+ν6 band is located. 1987 transitions were assigned to the ν2+ν6 band and 623 ro–vibrational energies of the (v2=v6=1) vibrational state were determined from the assigned transitions. Parameters of the effective Hamiltonian were determined from the weighted fit, which takes into account the studied (v2=v6=1) vibrational state and six other closely located (but experimentally here not visible) vibrational states of C2H2D2-cis. The obtained “experimental” energy values were used as initial information in the fit. Determined from the fit, a set of 95 parameters reproduces 623 initial energy values of the (v2=v6=1) vibrational state, representing 1987 line positions of the ν2+ν6 band with the drms=3.98×10−3 cm−1.
