Info and Contact
Our X-ray diffraction
instrumentation is available free of charge to
facilities of the larger American academic community and to regional
corporations on a time available basis. Space might be limited
periodically, and although we would
truly like to accommodate everyone, occasionally we will have to select
participants based on their background and the quality of the personal
statements.
Depending on your expertise and your interest, you may pick from one of
the following possibilities:
- You may book instrument time, come in and
collect
all the data yourself. Support will be provided by our faculty and
staff as needed.
- You can send in the sample, we collect the
data and
provide you with the hkl and p4p files
- You may send in the sample, we collect and
refine
the data (if the sample quality is sufficient) and provide you with the
final cif file ready for publication, summary tables as a word file, as
well as assistance upon publication and depositing of the data with one
of the databases
I order to apply for
either instrument time or to mail in a sample
please contact one of the following persons by e-mail
Our mailing
address is:
Department of Chemistry
Youngstown State University
1 University Plaza
Youngstown 44555-3663 Ohio
For single crystal
diffraction please also fill out the Single Crystal
Submission Form (
MS Word
or
Adobe PDF),
send it via e-mail to
mzeller@cc.ysu.edu
and mail a printed out copy together with your sample.
The usage of our X-Ray
facility is regulated by the YSU-S&CIF
X-Ray User Group. Details about the group and the User Guidelines can

And here some tips for mailing in samples:
- Not all crystals of one batch are equally
suitable
for single crystal diffraction. The larger the sample you send, the
more likely it will be
we will find the really good one.
- A large fraction of organic and organometallic
compounds are crystallizing with solvent incorporated into the crystal
lattice and are often prone to
desolvate as soon as they are taken out of the solvent. If you think
this
might be a problem for your sample, we recommend sending the crystals
in
their mother liquor. (Sealed glass tubes are a good choice)
- Long travel times often lead to decomposition
of
beforehand good crystals. Don't send samples on Friday afternoon. Pay
the extra buck for
speedy delivery.
- Lots of crystals are fragile. Make not only
sure
that your sample vial is well padded, but your crystals as well. Some
cotton wool in the vial usually does the job.
