- This elementary module represents the experimental results on LiBr2 and KI2. At first, we had created separate elementary modules for the three different types of collision partners: LiBr2, KI2 and KBr2. However, this distinction turned out to be too fine-grained. Following the expert opinion of prof. Los, we assume that readers do not consider collissions between different but comparable collision partners to be different subjects, so that readers will not be interested in consulting the different results separately. The reason why we still have represented the results on KBr2 in a separate elementary module, is that in the Interpretation those results are used as an example to make the discussion concrete.
