✦ Synopsis

In complex molecular spectra the identification of the pair of states corresponding to an observed transition energy is a difficult process. Erroneous assignments are hard to avoid. They cause fundamental difficulties when using least-squares procedures for estimating term values. On the other hand, a robust fitting method has proven extremely helpful for finding erroneous assignments and for obtaining reliable estimates of term values. These facts are demonstrated by applying both procedures to the estimation of term values in the (e^{3} \Sigma_{\mathrm{u}}^{+} \rightarrow a^{3} \Sigma_{\mathrm{g}}^{+})bands of (T_{2}).
