The calculated even levels of W i up to the height of about 40,000 cm-1, which is the height of the ground level of the d6 configuration, are reported. Fifty-seven observed levels are fitted to them, with a mean error of 100 cm-1. L-S coupling and configuration assignments are usually meaningless because of a very strong spin-orbit interaction and configuration interaction. For every level, the largest squared L-S coupling components of its eigenvector are reported, as well as observed and calculated g-values.
