Abstract

We report on the observation of magnetic dipole allowed transitions in the well-characterized A(2)Sigma(+) - X-2 Pi 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 Lambda-doublet components of the X-2 Pi(3/2), upsilon = 0, J = 3/2 ground state. Theoretical calculations presented in this Communication predict that the magnetic dipole transitions in the A(2)Sigma(+), upsilon = 1 <- X-2 Pi, upsilon = 0 band are weaker than the electric dipole transitions by a factor of 2.58 x 10(3) only, i.e., much less than commonly believed. Our experimental data confirm this prediction. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4751475]
