Answer to Question #87549 in Atomic and Nuclear Physics for Sridhar

Question

the transition J=0 to J=1 in a HCL molecule occurs at 10.08/cm. the rotational constant ?
Answer: 5.34

Answer 1

The rotational energy levels of HCL can be described using the rigid rotor model, which has energies

$$E_J=BJ(J+1) (1)$$

where E_J=10.68, J=1

Using (1) we got:

B=5.34

Answer:

5.34
