Figure 5
The dendrogram for a set of 11 organic powder patterns with two polymorphs. Samples 1–4 are form A; 8–11 are all form B; pattern 5 comprises 40% A and 60% B; pattern 6 is 50% A and 50% B, while set 7 contains 60% A and 40% B. The patterns for the mixtures have been simulated by adding the most representative sample of the pure forms with the required proportions. The data are partitioned into two groups, with the mixtures belonging to one or other of the sets. |
