Question

Discuss in detail the rotatinol-vibrational spectra of hertonuclear diatomic mol-ecules.

Answer 1

sryy i dont know this answer

Answer 2

In certainvibrational excited states themolecules do have a dipole moment so that a ro-vibrational spectrum can be observed in the infrared. ... For parallel transitions the selection rule is the same as for diatomic molecules, namely, the transition corresponding to the Q-branch is forbidden.
