Dear Bruce,<br><br>Could you please tell me if there is an option to do the EXAFS fitting for a compound having the absorbing atoms at two inequivalent crystallographic sites.<br><br>For example,<br><br>In Ca3Co2O6 compound, the Co ion occupies two inequivalent crystallographic sites with the Co1-O bond distance at 1.960 and Co2-O at 2.09 Ang. <br><br>How does one invoke the contribution of both the bond distances in the first shell fitting?<br><br>Best regards<br>Bindu<br> <br><br><br><BR><BR>Dr.Bindu R.<br>Visiting Fellow<br>DCMP&amp;MS<br>Tata Institute of Fundamental Research<br>Homi Bhabha Road<br>Colaba<br>Mumbai-400 005<br>India<br>Mobile-919892536830<p>&#32;
