Indirect evidence against the presence of C2 lines in umbral spectra is discussed. The dominant role of CO in the molecular equilibrium of C at umbral temperatures ensures that CN, CH and Cz lines are formed in the same atmospheric regions. Observations of CN and CH umbral lines are in good accord w

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

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.
