Introduction to Spectroscopy Q&A
Rotational Spectroscopy 1. What is the degeneracy of the rotational energy level with J = 4 for a heteronuclear diatomic molecule? 2. The A rotational constant of a phosphorus pentafluoride, PF 5 , molecule is 3.566 Hz. Calculate the lengths of the equatorial P-F bonds. 3. The rotational constant of ICl is 0.1142 cm-1. Calculate the bond length of the molecule.
