A new translation function T(t) is defined, whose main peak is expected to give directly the absolute position t = t0 of a known molecular configuration (the isostructural model) of known orientation in an unknown crystal structure. T(t) combines all required information: crystal symmetry, molecular steric properties of the model and experimental d...

In the general case where there is only one molecule in the asymmetric unit, and in the absence of non-crystallographic symmetry, molecular-replacement (MR) techniques can be used to solve an unknown crystal structure from a closely related known molecular model. The procedure comprises two stages in order to find (i) the orientation of the model i...

Nous présentons dans cette thèse la construction et l'analyse d'un modèle de structure compacte amorphe.Nous montrons dans une première partie qu'il est possible d'obtenir, avec un potentiel d'interactions atomiques donné, une structure aux caractéristiques reproductibles, possédant une forte densité et dont la fonction de corrélation de paires est...
