Selected Data

We have collected powderdata on several small organic molecules, and posted them here for people who might like to use them to test their indexing, structure solution, or other programs on real data. The available file formats are .xy (3 columns, 2theta, normalized counts, esd), .dat (fullprof data file, for INSTRUM=4), and .gda (GSAS). We intend to publish these patterns, as well as the (previously unknown) structures derived from them in the near future. All samples were purchased from Alfa Aesar. As far as we know, their structures have not been solved previously.

These patterns are offered without any representation of their accuracy, freedom from preferred orientation, detector zero offset, etc., although we believe that they are basically OK. If you think there is a problem, please contact Peter Stephens (peter.stephens@sunysb.edu). In all cases, the data were collected at beamline X3B1 of the NSLS, with Si(111) double crystal monochromator, and a Ge(111) analyzer.

Any person is welcome to download and use this data for test or demonstration purposes. However, if you forward this data to another person, or store it where it can be recovered by others (e.g. your own web page), or forward or store any analysis based on it, you should please include an acknowledgement of its source (this web page), and inform us of its use. The offer of free use does not extend to publication; do not publish results from this data, either in the open literature or for advertising purposes, without written permission from Peter Stephens. That restriction will not apply once we have published our own paper(s) on these results.
