A Bruker-ESP300e is mainly used for the studies requiring low temperature experiments (Oxford cryostat ITC-503 for measurments above 4K, B-VT 2000 for measurment above 100K) and for ENDOR and TRIPLE experiments (in the liquid phase).
A Bruker 200 is used for studying paramagnetic species produced by photolysis or electrolysis.
Additional home-made spectrometers are used for EPR measurments at 35 GHz and for single crystal ENDOR studies.
