The buffer gas loading and subsequent magnetic trapping of neutral molecules is a powerful tool for it provides samples of cold molecules with the highest densities known, while being applicable to a great variety of paramagnetic species. Metal-hydride molecules form an interesting class of molecules to study in such cold environments. Due to their complicated electronic structure, but still rather limited size, they form an appealing subject of study for quantum chemistry calculations. The possibillity to buffer gas load these molecules and confine them inside a trap at high densities would directly allow for the study of their intermolecular collisional properties.
To investigate the applicability of magnetically trapping CrH molecules, we have studied the Zeeman effect of CrH radicals produced in a molecular beam. The measured Zeeman structure is complex, but can theoretically well be described using an effective Hamiltonian treatment. Finally, the feasibility of buffer-gas loading of these interesting radicals is discussed.
