Abstract
We report on the observation of magnetic dipole allowed transitions in the well-characterized band system of the OH radical. A Stark decelerator in combination with microwave Rabi spectroscopy is used to control the populations in selected hyperfine levels of both -doublet components of the ground state. Theoretical calculations presented in this paper predict that the magnetic dipole transitions in the band are weaker than the electric dipole transitions by a factor of only, i.e., much less than commonly believed. Our experimental data confirm this prediction.
