Progress in atomic structure calculations together with todays fast computers make it possible to accurately compute many spectroscopic properties in atoms and ions. Among these properties are oscillator strengths, but also hyperfine structures and isotopes shifts that broadens and shifts lines in high resolution stellar spectra. Lande g_J factors as well as splittings in intermediate and strong magnetic fields can be calculated with high accuracy. In this work we present some calculations that reflects the status of the computational methods.
