Title: X-Ray Crystallography problem
Post by: Dolphinsiu on December 16, 2006, 04:57:11 AM

A student grows a crystal of an unknown compund in an organic solvent.Suggest a suitable X-ray crystallography method for him to determine the crystal structure and how he can apply the technique. Draw a simple diagram with brief notes to illustrate your answer.

How can I find websites that related to this question? as I haven't been taught about this issue! Also I only know X-ray crystallography can predict the structure is f.c.c or h.c.p.etc. whereas infrared spectrography is to predict the bonds by skretching or bending! Please *delete me* Thank you!

Look into single crystal X-ray diffraction. This has to be one of the coolest techniques ever. You run your crystal, process the pattern and it literally draws a picture of the molecule.

this may be helpful http://en.wikipedia.org/wiki/X-ray_crystallography#Single_Crystal_Diffraction

But I'd recommend getting hold of McKie & McKie "Essentials of crystallography"
