Stark effect (shifting and splitting spectral lines due to external electric field) is calculated in nearly all QM textbooks as application of perturbation theory (alongside Zeeman).

Wikipedia article ( https://en.wikipedia.org/wiki/Stark_effect ) has a nice figure with n-th level splitting into n-1

It is hard to find published experimental results - please cite if you know some.

A clear one for Lyman series (2->1, 3->1, 4->1) can be found in historical "Der Starkeffect der Lymanserie" by Rudolf Frerichs, published January 1934 in Annalen der Physic (its editors back then: W. Gerlach, F. Pashen, M. Planck, R. Pohl, A. Sommerfeld and M. Wien), here are its results:

These are clearly

**not uniformly distributed**- how to understand/repair this discrepancy?
