Resonant photon absorption in the GHz range was observed via
low-temperature micro-SQUID magnetization measurements of the spin
ground state 
of the molecular complex . A
simple single-molecule interpretation is proposed. The line width
essentially results from intra-molecular hyperfine interaction.
The results point out that observing Rabi oscillations in
molecular nanomagnets requires well-isolated low-spin systems and
high radiation power.
