• The rotation-vibration spectrum of ν<SUB>6</SUB> of acetonitrile measured by Nakagawa <I>et al.</I> has been reanalyzed by taking account of the Fermi resonance between the states |<I>v</I><SUB>6</SUB>=1> and |<I>v</I><SUB>7</SUB>=1, <I>v</I><SUB>8</SUB>=1>. The previous assignment of <I>Q</I> branches by Amat <I>et al.</I> has been revised on the basis of the obtained values of band constants. The following band constants have been determined for the ν<SUB>6</SUB> band: ν<SUB>0</SUB>=1447.9 cm<SUP>−1</SUP>, ζ=−0.305 and α<I><SUP>A</SUP></I>=0.046 cm<SUP>−1</SUP>. From the value of the resonance operator, the magnitude of the cubic force constant <I>k</I><SUB>678</SUB> has been estimated to be about 30 cm<SUP>−1</SUP>.
