1. could anyone give sorta a qualititative explanation of how symmetry and irreducible representation are related in the context of molecular spectroscopy? like why is it so useful to count how many symmetries a molecule has and what does it have to do with irreducible represenations and spectroscopy?(adsbygoogle = window.adsbygoogle || []).push({});

2. could anyone point me to a book/website with a lucid discussion of it -- preferrably an explanation fit for a physicist (like one rife with examples and explanations not like thm/remark/proof style).

im reading sternberg right now -- its good, but its still confusing.
