Answer 1

Answer:

IDK

Explanation:

Answer 2

Explanation:

Rotational Transitions, Diatomic

For a rigid rotor diatomic molecule, the selection rules for rotational transitions are ΔJ = +/-1, ΔMJ = 0 . The rotational spectrum of a diatomic molecule consists of a series of equally spaced absorption lines, typically in the microwave region of the electromagnetic spectrum.
