Vibration-rotation bands in ethane

The absorption spectrum of ethane was recorded at 0.014 cm−1 resolution in the range 4500–6500 cm−1 using a Fourier transform spectrometer and at room temperature. Eighteen bands could be identified and their type assigned. Upper state rotational constants are provided for the band at 5948.338 cm−1 and Coriolis constants are obtained for most perpendicular bands. Vibrational assignments are suggested for the bands at 5948 cm−1 (v7 + v10), 5914 cm−1(v8 + v 10+ v 11), and 5852cm−1 (v 5+v 10). All vibrational bands reported in the literature are gathered.
