Dear Dharmveer Bhatia,
In this article there is all data for the distance Ti-O in the anatase structure.
Sincerely
Professor Pavel Kudryavtsev
I would check the icsd website for crystallographic information on anatase. This will give initial information on the Ti-O bond lengths from several different publications (http://icsd.cds.rsc.org/search/basic.xhtml).
Then you can use the crystallographic information to perform Rietveld analyses on XRD from your samples to refine the published structures to your samples to determine the T-O bond lengths in you system.
Another method to determine the bond Ti-O bond lengths in your samples is to perform Ti X-ray absorption spectroscopy using synchrotron radiation (http://www.cat.gov.in/technology/accel/srul/beamlines/mcd_pes.html).
Dear Kenneth M Towe,
If the product is a solid solution having an anatase structure, small changes in the length of bonds Ti-O, are possible.
Yours faithfully
Pavel Kudryavtsev
I do not know what his system, specifically. But, previously, in the preparation of inorganic sorbents based on TiO2, we observed the formation of solid solutions with anatase structure. At the same time we have seen little changes in the unit cell parameters of the anatase, and therefore small distortion parameters of the octahedra TiO6. Therefore, I consider that the length of the Ti-O bonds cannot be accurately fixed.
@Dharmveer Bhatia
Since you don't tell us what your materials system is or any specific details regarding which Ti-O you are talking about, so here is what I can suggest you:
You need to determine the lattice parameter of your sample, that means you need to do a little bit calculation based on your diffraction pattern. Then you draw the crystal structure according to the parameter you have. You can use any crystal simulation software to do it, suppose Diamond or Carine. From there you can determine any length and angle between atoms or planes. Hope this is what you are looking for.
You should perform the Rietveld refinement using fullprof of your xrd data. You can easly find it there.
