a 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 ransition frequencies within their standard deviations.

b Assuming planarity conditions.

c Since A″ and τaaaa are directly correlated, τaaaa had to be fixed at zero in this analysis.

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