✦ Synopsis

The luminescent state of [ Rh (bpy ), ] ( C104)., (bpy = 2,2'-bipyridine) has been studied by means of low-field optically detected magnetic resonance (ODMR) spectroscopy. Experiments performed on single crystals, at low temperatures (Tz 1.4 K), revealed a magnetic anisotropy characteristic of a ligand-centered %-x* excitation. Furthermore, the experimental results show that the excitation is trapped on one single ligand molecule per Rh3+ cation site only.
