a The uncertainties quoted are one standared deviation as estimated by the least squares fit. The number of significant figures quoted are necessary to reproduce the calculated transition frequencies within their standard deviations.b The A rotational constant was fixed at this value from infrared measurements [67026]. Since τaaaa was indeterminable it is fixed at zero.
c Strictly speaking, τ3 is not a determinable parameter, but is calculated from τ1, τ2, τaaaa, and τbbbb using the planarity conditions.
