We report high-resolution Doppler-free hyperfine-structure determinations of eight excited levels in the first spectrum of zirconium. These structures have been obtained with optogalvanic intermodulated saturation and Polinex spectroscopic techniques on a zirconium vapor formed in a hollow-cathode-type generator. Quantitative values for the hyperfine splittings and for the A and B constants are given for the levels at

of the configuration 4d25s5pz and of the level at 15 120 cm−1 of the configuration 4d35sa3H6.

F1 and F2, total angular momentum of lower and upper hyperfine sublevels; |Δν(F1, F2)|, absolute values of hyperfine sublevel separations.
From our measurements (intermodulated and Polinex spectroscopy).
Deduced from the data of Ref. 7 for the three lower levels of the ground-state configuration and from these data and our measurements for all the upper levels.
