Notes. Uncertainties on the measured intensities are typically ≤10% (written as the subscript), as determined from Gaussian fitting. 1) None detection is given by an upper limit of 3σ rms; 2) integrated intensities are obtained by Gildas “Gaussian” fittings; 3) laboratory parameters are given from CDMS; 4) Q(300 K, CH3CN) = 14 683.6324; 5) Q(300 K, ) = 199 602.70.
