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

The expected equivalent widths of individual rotational lines of the most intense 02 branch of the 0--0 band of the AaX--X2Hi system of $32H and 534H have been calculated in the umbral spectrum for five disk positions using Zwaan's (1974) sunspot model. Percentage abundance of S 34 in the terrestria
The equivalent widths of the TiO lines in the a system have been measured on a high dispersion (11 mm/A,) spectrogram of large sunspot. The lines were so weak that the measurement was made by methods giving maximum and minimum equivalent widths, depending on the adopted continuum. The rotational tem
