Q10(b). Rotational constant from a rotational Raman spectrum
In the pure rotational Raman spectrum of a diatomic molecule, the first three transitions are observed at 26.52, 44.20 and 61.88 cm⁻¹. (i) Calculate the rotational constant B of the molecule. (ii) What other information would you need to calculate the equilibrium bond length of the molecule? Explain your answer.
