    Sammanfattning : This survey presents six previously published papers dealing with time-resolved atomic and molecular spectroscopy with applications to the chemical composition of the solar atmosphere. Three methods of measuring mean lives of excited states have been used:Beam-foil spectroscopy Beam-laser spectroscopy High-frequency deflectionThe methods used to estimate the abundances of the chemical elements in the sun will also be outlined.
