Magnetic dipole transitions in the OH $A{}^2{\Sigma }^{+}\leftarrow X{}^2\Pi$ system

Moritz Kirste, Xingan Wang, Gerard Meijer +4

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…
