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

NOTE: The uncertainties quoted are one standard 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.
