Popis: We have observed fine-structure intervals in Cs I using high-resolution Fourier spectroscopy. Improved values are reported for the $5,6^{2}D$ and $4\ensuremath{-}9^{2}F$ terms and are shown to be consistent with recent laser fluorescence measurements of the $10\ensuremath{-}17^{2}F$ intervals. The results are compared with previous measurements. A three-term expansion in odd powers of $\frac{1}{{n}^{*}}$ is shown to describe all of the $4\ensuremath{-}17^{2}F$ fine-structure intervals. The state of experimental and theoretical work on the doublet structure in the alkali metals is briefly reviewed.
