Abstract
A fourier transform interferometer was used to record the slit jet cooled overtone absorption $spectrum^{a}$ of $^{12}C_{2}H_{4}$ between 3900 and $7900cm^{-1}$ at a spectral resolution of $0.02cm^{1}$ and a rotational temperature of 53K. In this high frequency range. We perform the analysis of 17 combination bands. For some of them located at 4206, 4322, 4328, 4515, 4730, 5995, and $6150cm^{-1}$ the analysis was complicated by the existence of A-type B-type and C-type Coriolis-type resonances with dark states. For each analysed spectral region, a preliminary calculation of the energy levels was performed taking into account the observed resonances.
