Author Institution: Theoretical Division, Los Alamos Scientific Laboratory; Department of Physics and Astronomy, University of TennesseeThe Q branches PQ6β through RQ9β of the Ξ½9β ethane fundamental at 821 cmβl have been resolved at 300βK using tunable diode lasers. A preliminary analysis yields ΞB=(β1.27Β±0.02)Γ10β3cmβ1. Several of the branches exhibit line splittings that may result from the tunneling of the hindered rotation of the ethane molecule
