High resolution coudé spectra in the blue and violet spectral regions have been obtained for five G dwarfs. Model atmospheres and spectrum synthesis of selected iron lines have been performed. Thegf values as well as other atomic parameters used in this analysis were previously tested by means of a solar model and the UtrechtSolar Atlas. Revised iron abundances have been derived. Some tentative evidence is presented that these abundances are related with the Wilson-Bappu width of Ca ii emissions.
