Figure 5
Variation of the open-circuit potential (OCP) with time during measurement of the XANES of [CuCl(bpy)2]+ (Fig. 4[link]). The timescale for the full-beam trace was adjusted so that the shutter is closed at time t = 0 s. Prior to the start of each scan the alignment of the four-bounce monochromator axes is checked, and this gives a reproducible set of variations in the beam intensity. A wider scan range was applied for the attenuated-beam scan. The start and end of the full- and attenuated-beam measurements were aligned by extracting a block of measurements during the longer attenuated-beam scan. The full OCP data for the attenuated-beam measurements and a more detailed description of the monochromator alignment routine are given in Section S4 of the supporting information.
