Question

Number of IR active modes of CIF3 is​

Answer 1

Answer:

By inspection of the character table, the 2T2 modes are IR active and A1, E, and 2T2 modes are Raman active.Water has three normal modes of vibration, all of which are IR active. Carbon dioxide, a linear molecule, has 4 normal modes of vibration. Even though it does not have a permanent dipole moment, the dipole moment changes during 3 of the 4 modes, so carbon dioxide can absorb in the IR.

Answer 2

Answer:

Here is your answer

Explanation:

1. By inspection of the character table, the 2T2 modes are IR active and A1, E, and 2T2 modes are Raman active.
