Three experts will guide you through the many pitfalls awaiting for the diffractionists wishing to determine a structure from powder data:

    Alain Jouanneaux, Maître de Conférence,
   Yvon Laligant, Chargé de Recherche CNRS, and 
    Armel Le Bail, Directeur de Recherche CNRS.

They totalize together more than 40 SDPDs since 1987 (>10% of all the structures determined from powder data in the past, which are listed in the SDPD Database, searchable by keywords).

They are also authors of papers on methods related to powder diffraction and of software (WinMprof, ESPOIR, OVERLAP...) as well as of tutorials and conferences, some being available on the Web.
