How many normal modes of vibration are there for the following molecules: (i) C6H6 (ii) C6H5CH3 (iii) HC≡C-C≡CH
Added by Norman M.
Step 1
In general, a molecule with N atoms has 3N degrees of freedom. However, we need to subtract the 3 translational and 3 rotational degrees of freedom, leaving us with 3N - 6 vibrational degrees of freedom for non-linear molecules. Show more…
