β¦ Synopsis
intensity factors for bands of the C-A transition of the A1F molecule are calculated. A reinvestigation for the lines of (0, 0) band of the C-A system in sunspot spectra is suggested, so as to resolve the question~tble existence of A1F absorption lines in sunspots.

For use in the investigations of magnesium monoxide lines in sunspot spectra, values of Franck-Condon intensity factors for the red bands and the wavelength regions for the intense bands of the red and near-ultraviolet transitions of MgO are presented. The results indicate that a search for the line
We show empirically how the effect of the instrumental polarization of the spectrograph can distort the shape of the intensity profiles in sunspots. In order to avoid the problems an analysis of the polarization of the. light should be performed at the entrance slit of the spectrograph.
