The Sun with its low density atmosphere provides us with a unique astrophysical laboratory to test some of the interesting and rare atomic effects. These effects are often not observed in the terrestrial laboratories. One such is the quantum mechanical interference between the atomic states. This talk discusses the signatures of these interferences in the polarized spectrum of the Sun and our efforts in modeling them. A detailed comparison between the observed and synthesized profiles will be presented, with a few examples. Finally, the diagnostic potential of such atomic lines for the measurement of chromospheric magnetic fields will be discussed.
