. Consider the three isomers of the trichlorinated benzene compound, C6H3Cl3. (a) Draw each isomer, name it and determine its point group. (b) Using ONLY the C-Cl bonds as a basis set, determine C-Cl for each system and break it down into the corresponding irreducible representations. (c) For each isomer, indicate how many IR and Raman Peaks should be observable corresponding to the C-Cl stretching frequency. Perhaps a table to summarize your results would be appropriate.

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.

the spectrum and identify each unique proton. Indicate which proton
is responsible for each peak.

responsible for each important peak. Attempt to identify at least
five important peaks. In you discussion, indicate which peaks are
most helpful in determining whether or not you converted the
starting material to the desired product.
