Query: Photoassociation of rovibrational Rydberg molecules   In this work we discuss the rotational structure of Rydberg molecules. We
calculate the complete wave function in a laboratory fixed frame and derive the
transition matrix elements for the pho- toassociation of free ground state
atoms. We discuss the implications for the excitation of different rotational
states as well as the shape of the angular nuclear wave function. We find a
rather com- plex shape and unintuitive coupling strengths, depending on the
angular momenta coupling that are relevant for the states. This work explains
the different steps to calculate the wave functions and the transition matrix
elements in a way, that they can be directly transferred to different molecular
states, atomic species or molecular coupling cases.
