Hi, Researchers,
Recently, I am learning a tutorial of the Rietveld refinement online. It says that the structure factor of P42/mnm TiO2 can be expressed as the plot1 shows, the A factor.
I want to know, in which references I can search the structure factor expressions for other space groups, such as R-3m. I mailed the author and am told that They are all listed in the old international tables vol a (red cover version). But, I can not find it as it is too old.
Cuould someone recommend some other references for that ?
Just an addition there are some of the old tables available at archive.org including vol 1.

Dominique

Dear Xu Mingquan,
please have a look at the attachment
There is a copy of page 469 and 462 of the chapter 4.7. (Geometrical Structure Factors and Electron Density Formulae for the Three-Dimensional Space Groups) from International Tables for X-ray Crystallography Vol. I. (1952)
Dear Gerhard Martens,
Thanks a lot for your reply. It is very helpful.
The copy you provided is about R3m which No. 160 space group, while what I want is No. 166 space group, namely R-3m.
In addition, may I ask you for the Structure Factor Expressions for No. 12, No.166, No. 225 and No. 227, or the full copy of chapter for structure factor expreesions in International Tables for X-ray Crystallography Vol. I. (1952). It is so old that I can not find it.
I will appreciate it.
Best regards
Dear Xu,
copying the whole chapter is a very boring Job (152 pages).
But for the few ones I am pleased to do that.
Please see the Structure Factor Expression for No. 12, 116, 225 and 227 in the attached file. Please note that the No. 12 has got 2 pages and No. 227 has got three pages. In addtition there were some cross-references within that chapter mentioned. I have copied them too. The pages are all ordered acoording to the page numbers in the book.
If you have additional requests you may aks for via Researchgate messenger.
Best regards
Dear Gerhard Martens,
It is very nice of you to send me the attached file and I appreciate it very much.
Thanks a lot.
