Hi Hana:<br><br>I would add that you should expect your sigma2 values to be smaller or the same since you collected  data at 10K in comparison to those collected at room temperature.  If the origin of the disorder is thermal then your sigma2 values will be a smaller than the RT ones. If the orgin of the dissorder is structural/static then your sigma2 values will be about the same.  That all asumes that the RT sigma2 values are correct, which they might be.<br>
<br>2cents worth,<br>Shelly<br><br><div class="gmail_quote">On Fri, Jun 17, 2011 at 2:30 PM, Hana <span dir="ltr">&lt;<a href="mailto:hana63.new@gmail.com">hana63.new@gmail.com</a>&gt;</span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Dear EXAFS experts,<br>
I am quite a beginner, and that&#39;s might be an ignorant question but really<br>
important to my work, so I would be happy to get a direction:<br>
what would be the right way to weigh in the effect of temperature in soils<br>
samples, since solutions like Debye models will not fit to my understanding?<br>
specifically, I am trying to compare my measurements(collected at 10K) to<br>
literature data of these metals adsorbed on iron oxides (collected at room<br>
temperature).<br>
<br>
I would appreciate any advise,<br>
Hana<br>
