1. Vibrational spectroscopy: Bond-stretching vibrations. Sadly, labels have fallen off of two vials containing manganese(I) carbonyl coordination complexes. Thus, a chemist is unsure which vial contains [Mn(CO)sCl] and which contains the sodium salt of trans-[Mn(CO)4C2]. Not easily deterred the chemist acquires an IR spectrum of the contents of one of the vials. Below are the structures of the two possible complexes (left) and the CO-stretching region of the IR spectrum (right) [Mn(Co),CI] trans-[Mn(Co).CIJ10 Cl CI CI 2200...
