Sports Volunteers Around the Globeds would still be an esoteric, little used branch of crystallography rather than the most important technique available for solving the structures of ‘small’ molecules. The packages which will be discussed here are (in alphabetical order):

Direct methods try to evaluate phases . “directly” from the measured diffraction intensities I. by using relationships among the phases, relationships, whose values are based on the
