✦ Synopsis

The jet-cooled spectrum of ethane in the region of the nu8 perpendicular fundamental vibration at 1472 cm-1 was recorded with a Fourier transform spectrometer at 0.01 cm-1 instrumental resolution. About 1150 lines were assigned to 18 subbands of nu8 ranging from K"DeltaK = -9 to +8. About 160 lines were assigned to three subbands (K"DeltaK = 0 to +2) of the nu4 + nu12 combination band near 1481 cm-1. Torsional splittings were observed for the majority of the transitions. A stack-by-stack analysis was performed, resulting in effective rovibrational parameters for the upper states nu8 and nu4 + nu12. A number of perturbations was observed and is discussed.
