^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 Strictly speaking, τ₃ is not a determinable parameter, but is calculated from τ₁, τ₂, τ_aaaa, and τ_bbbb using the planarity conditions.
