Abstract
The paper discusses several feasibility prediction criteria with particular emphasis on light atom molecules. For several examples of refined absolute structures, feasibility predictions are calculated and compared with a posteriori calculated values of the Bijvoet ratio. An extension of the Pathasarathy table of the expected value of the Bijvoet ratio is given for parameter ranges corresponding to light anomalous scatters. Practical conclusions are drawn for absolute structure determination of compounds containing oxygen or nitrogen as anomalous scatterers.Keywords
