Question

Which of the following molecule exhibit rotational and or vibrational spectra H2 ,HF ,CO, NO ?

Answer 1

only H2 will not exhibit the rotational and vib spectra because it is homo diatomic molecule n it is non polar

Answer 2

Answer:

HF is the molecule of exhibit rotation and or vibrational spectra.

Explanation:

Exhibit rotation energies corresponds to microwave spectra. Vibrational energies corresponds to infrared radiations. HF is a molecule of diatom, which accepts the molecules in gas phase.

The sequence of quantized rotation levels are associated with ground state and excited state.

The changes that happened in rotational energy levels are much smaller than the changes in vibration energy levels. Due to this changes rotational energy gives exact structure to the vibrational spectra.
