A new value of the solar photospheric abundance of iron, independent of line-shape parameters, is derived. Our analysis is based on a study of 40 weak infrared lines (0.85<2<2.5/-0 for which theoretical oscillator strengths (calculated with configuration interactions taken into account) have recentl
High precision center-limb spectrograms of the K I resonance doublet line at 27699 A were used to study the line formation and to determine the abundance of potassium in the solar atmosphere. The LTE assumption is not valid for these lines. Synthetic profiles computed in NLTE reproduce very well the
