Some Exercises in Direct Methods
This chapter consists primarily from a table of triplet relations which should be used in practical exercises. The triplets belong to a triclinic centrosymmetric structure (space group P1bar) of code name WILLES. It is a steroid with 20 ‘heavy’ atoms and formula C17H23NO2. The cell constants are a = 8.505, b = 8.688, c = 13.513 A, α =125.00, β = 96.51, and ? = 106.46°.
