Normal Modes of Vibration in N2O
Normal modes of vibrations refer to the different ways in which a molecule can vibrate when subjected to energy. In the case of N2O, there are four normal modes of vibrations:
1. Symmetric Stretching (ν1)
This mode involves the stretching of the N-N bond in a symmetric fashion. This vibration results in a change in dipole moment and is IR active.
2. Asymmetric Stretching (ν2)
This mode involves the stretching of the N-N bond in an asymmetric fashion. This vibration also results in a change in dipole moment and is IR active.
3. Scissoring (ν3)
This mode involves the bending of the N-N-O bond angle. This vibration does not result in a change in dipole moment and is not IR active.
4. Rocking (ν4)
This mode involves the bending of the N-N bond angle. This vibration does not result in a change in dipole moment and is not IR active.
Therefore, there are a total of four normal modes of vibrations in N2O.

N2O is linear so, linear formula is 3N-5
(3×no of molecules -5)
=3×3-5
=9-5
= 4
