The pure rotational spectrum of a diatomic molecule like CO2 can be analyzed using spectroscopy. In rotational spectroscopy, transitions between different rotational energy levels are observed, and these transitions result in spectral lines. The pure rotational spectrum of CO2 can be explained by considering the rotational energy levels of the molecule.

In the case of CO2, it is a linear molecule with three atoms. The rotational energy levels for a diatomic molecule are given by the expression:

\[ E_J = J(J + 1) \dfrac{\hbar^2}{2I} \]
