A Theoretical Analysis of the Magnetic Hyperfine Structure of the Microwave Spectrum of C_2v Molecules

抄録

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_2v molecules in ¹A 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 ΔJ=0, ΔK₊₁=−1, and both initial and final K₋₁ values are odd.
