The most important quantitative aspects of computational structural crystallography can be
introduced in a satisfactory way using 1D truncated and periodic Gaussian functions to represent the
atoms in a crystal lattice. This paper describes in detail and demonstrates 1D structural
crystallography starting with the definition of such truncated Gaussians. The availability of the
computer programme CRONE makes possible the repetition of the examples provided in the paper as well
as the creation of new ones.
