Question

When j = 1, What is the energy level Ej in rotational spectra ? a. 2B
b. 6B
c. 12B
d. 8b​

Answer 1

Answer:

6b is the answer

Explanation:

hope it helps!

Answer 2

Given: The value of J is 1.

To find: We have to find the energy Ej.

Solution:

The energy expression for rotational spectra is given as-

Ej=BJ(J+1)

Where B is the rotational constant of the rotational spectrum.

J is the rotational quantum number.

The given value of J is 1.

Putting the value in the above equation we get-

Ej=B×1(1+1)

Ej=2B.

Thus the energy Ej is equal to 2B.

Hence the correct option is a.
