List the numbers of translational, ratational, and vibrational degrees of freedom of NNO (a linear molecule) and NH_3Solution
Degree if free for linear and non linear molecules can be given as
Linear molecule
Non Linear molecule
Tansitional degree of freedom
3
3
Rotational degree of freedom
2
3
Vibrational degree of fredom
3N-5
3N-6
Total
3N
3N
Here, N is the number of atoms in the molecules.
Therefore for NNO (Linear molecule)
Linear molecule (NNO)
Tansitional degree of freedom
3
Rotational degree of freedom
2
Vibrational degree of fredom
3(3)-5 =4
Total
3(3) = 9
For NH3 molcules which is non linear
Non Linear molecule (NH3 )
Tansitional degree of freedom
3
Rotational degree of freedom
3
Vibrational degree of fredom
3(4)-6 = 6
Total
3(4) = 12
| Linear molecule | Non Linear molecule | |
| Tansitional degree of freedom | 3 | 3 |
| Rotational degree of freedom | 2 | 3 |
| Vibrational degree of fredom | 3N-5 | 3N-6 |
| Total | 3N | 3N |
