Alert level A ABSTM02_ALERT_3_A The ratio of expected to reported Tmax/Tmin(RR') is < 0.50 Tmin and Tmax reported: 0.350 0.990 Tmin(prime) and Tmax expected: 0.986 0.993 RR(prime) = 0.356 Please check that your absorption correction is appropriate.
|Author Response: The crystal was grown from the melt in situ on the diffracometer. It gave the strongest intensities from a group of crystals that were also present in the capillary. As it appeared to be located at the side of this group (i.e. more towards the wall of the capillary) the absorption correction had to accommodate the highly anisotropic absorption paths through the sample.|
SADABS was also used to correct for the decay of the synchrotron x-ray beam which contributes to an apparent anisotropy as the data collection progresses.
