is the spectral linewidth something that is only explained by the uncertainty principle or do you also get this from schrödinger's equation? cause i would say, that schrödinger gives us discrete energy levels if we talk about atoms and therefore there should appear no linewidth.(adsbygoogle = window.adsbygoogle || []).push({});

or do i need to take quantum electrodynamics into account to make proper predictions of spectral lines?
