ESPOIR is a Reverse Monte Carlo code for ab initio crystal
structure determination by fittting to "|Fobs|" extracted by
powder diffractometry.
Improvements in the new release, ESPOIR 1.0, include :
- Choosing any space group, not only P1.
- Annealing by reducing progressively the amplitude of atom moves.
- Accepting events that do not improve the fit that helps not getting
trapped in false minima.
- Restarting automatically when false minima still exist.
- Optimization of the |F| calculation, saving time.
- New examples including the SDPD Round Robin sample I
[Co(NH3)5CO3]NO3.H2O, and cimetidine C10H16N6S.
