Figure 2
Crystals of [HNCH2CH2NHCRe(2,2′-bipyridine)(CO)3]Br mounted on a glass fibre, centred on the φ axis of the ID9 beamline at the ESRF and subjected to a laser beam of λ = 400 nm at 50 µJ (Cole et al., 2003). (a) and (b) are different views of a crystal of 90 µm diameter in the laser-beam direction post-irradiation; (c), (d) and (e) relate to the 40 × 50 × 60 µm crystal ultimately used in the case study before, during and after laser irradiation, respectively. Note that the view of the crystal in (e) is slightly obscured by ice that formed around the crystal during the experiment. Only amorphous contributions due to the icing were observed in the diffraction patterns. |
