[sdpd] UPPW11 part 2

[Armel Le Bail <alb...@cristal.org>]

Hello,

UPPW-11 - Part 2
February 7, 2004

Problem :Bethanechol chloride C7H17ClN2O2

Not any result last week for 
<http://www.cristal.org/uppw/uppw11.html>two ICDD entries (43-1748
and 46-1964), both Grant-in-Aid, this was an interesting
case for investing more efforts.

Two new powder patterns were recorded, one from conventional
X-ray data and the other from synchrotron radiation. Try to
index with both data for comparison. See the peak positions at :
http://www.cristal.org/uppw/uppw11-2.html

The raw data are also available, so that you may try by
yourself to extract the peak positions or to apply a software
needing the whole powder pattern for indexing (see the readme.txt
file inside of the .zip file) :

Best wishes,

Armel

PS - One day late for this UPPW is because the main synchrotron
problem is now identified : time needed for sending the sample + time
awaiting for the beamline availability. During 1/5 of all that time, a
conventional  X-ray pattern is recorded, and the structure is already
solved and refined ;-).
