On the basis of an analysis of echelle polarization spectrograms of different sunspots obtained with the Solar Tower Telescope at the Crimean Astrophysical Observatory, it is shown that the Zeeman splitting characteristics of Fe II (6302.5 A) and Fe I (5250.2 A) lines are the same. It is suggested that the presence of Fe II lines in the spectra of spot umbrae is due to bright umbral points. It is concluded that magnetic field polarity in the bright umbral points is the same as in the main magnetic fields of sunspots. 17 references.
