Question

calculate
number of modes of vibration for
C6H6 and co₂ molecule​

Answer 1

Answer:

The benzene ( ) contains 12 atoms. Therefore, Hence, the number of vibrational modes is 30.

Each absorption in a vibrational spectrum corresponds to a normal mode. The four normal modes of carbon dioxide, Figure 1, are the symmetric stretch, the asymmetric stretch and two bending modes. The two bending modes have the same energy and differ only in the direction of the bending motion.
