Abstract
This paper discusses the determination of the abundances of carbon, nitrogen and oxygen in the solar atmosphere from an analysis of atomic and molecular spectra. A detailed discussion of the neutral atomic spectra is presented. Five molecular bands are considered: C 2 Swan Band, CN red and violet systems, CO first overtone bands, and the CH ( A2 Δ− X2 Π) band. With the exception of the CH band, the analysis of the molecular bands yields abundances which are in good accord with the results from the neutral atomic spectra. The following abundances are derived: log AC = 8.55, log AN = 7.93 and log AO = 8.77 on the standard scale log NH = 12.00.Keywords
