Explanation:

Effects of magnetic field on microwave absorption spectrum

When a weak magnetic field is applied to a molecule, it can cause a splitting in the microwave absorption spectrum. This is known as the Zeeman effect.

Splitting of a spectral line

In this case, a single line in the microwave absorption spectrum splits into 3 lines upon application of the magnetic field.

Relation between splitting and quantum number J

The number of lines that appear in the split spectrum is directly related to the quantum number (J) of the rotational energy level from which the transition originates.

Relation between number of lines and J

- If J = 0 or 1, only one line will appear in the split spectrum.
- If J = 2, three lines will appear in the split spectrum.
- If J = 3, five lines will appear in the split spectrum.

Answer:

In this case, since only 3 lines appear in the split spectrum, the quantum number (J) of the rotational energy level from which the transition originates must be 0. Therefore, the correct answer is option 'A'.
