A Theoretical Analysis of the Magnetic Hyperfine Structure of the Microwave Spectrum of C2vMolecules

A theoretical analysis of magnetic hyperfine structure due to the magnetic interaction between the spins of off or on axis nuclei and the molecular rotational magnetic field is developed for asymmetric C 2 v molecules in 1 A electronic and vibrational ground state. This analysis is for the special case where two equivalent nuclei of spin 1/2 are off the molecular axis, one nucleus of spin zero and one nucleus of arbitrary spin are on the molecular axis. This analysis predicts that a triplet will be observed for prolate rotational transitions for which Δ J =0, Δ K +1 =-1, and both initial and final K -1 values are odd.
