A combined single crystal neutron/X-ray diffraction and solid-state nuclear magnetic resonance study of the hybrid perovskites CH 3 NH 3 PbX 3 (X = I, Br and Cl)

This article describes a variable temperature solid-state NMR and single crystal X-ray/neutron diffraction study of the hybrid perovskites (CH 3 NH 3 )PbX 3 (X = I, Br and Cl).
