955<p class=MsoNormal>In these exercises you will use GSAS-II to solve the
956structures of 3-aminoquinoline and &#945;-d-lactose monohydrate from powder
957diffraction data via Monte Carlo/Simulated Annealing (MC/SA). The data sets
958were kindly provided by Peter Stephens (SUNY <span class=SpellE>StonyBrook</span>)
959and were originally collected on NSLS beam line X3b1. The MC/SA technique is
960needed in these cases because as you will see the data does not extend very far
961in 2&#920; so one cannot use charge flipping to solve them. The steps for each
962begin with peak selection and fitting, then indexing to identify the lattice
963parameters. A Pawley refinement is used to obtain a set of structure factors
964needed for the MC/SA runs. We will use previously developed models for the two
965molecules; I used the freeware program Avogadro (<a
966href="http://avogadro.cc/wiki/Main_Page">http://avogadro.cc/wiki/Main_Page</a>)
967to create them.</p>

1658<p class=MsoNormal>If you are lucky (like I was!) then the result is clearly a
1659good solution with a very low Residual (~4.8%). This problem typically gives
1660suitable solutions with Residuals of 4-5%. If no good solution appears (e.g.
1661molecules clashing), then you should just rerun MC/SA perhaps using more runs
1662or more trials. Be sure to set the <b style='mso-bidi-font-weight:normal'><span

1675<p class=MsoNormal>MC/SA refinement is achieved by narrowing the search ranges
