Talk:Misorientation

Untitled
Hi

I've tried to follow the example about Copper and S3 given in the article. Inserting the Euler angles for Cu and S3 given into the orientation matrix g:

$$\begin{bmatrix} c\phi_{1}c\phi_{2}-s\phi_{1}s\phi{2}c\Phi & s\phi_{1}c\phi_{2}-c\phi_{1}s\phi{2}c\Phi & s\phi_{2}s\Phi\\ -c\phi_{1}s\phi_{2}-s\phi_{1}c\phi{2}c\Phi & -s\phi_{1}s\phi_{2}+c\phi_{1}c\phi{2}c\Phi & c\phi_{2}s\Phi\\ s\phi_{1}s\Phi & -c\phi_{1}s\Phi & c\Phi \end{bmatrix}$$

does not give the shown results for $$g_{copper}$$ and $$g_{S3}$$. In order to obtain the shown results, following changes to the orientation matrix have to be done:

-- All $$\phi_{2}$$ and $$\phi{2}$$ have to be changed to $$\phi_{3}$$

-- All $$\Phi$$ have to be changed to $$\phi_{2}$$

-- The second sign (minus sign) in element 1,2 (row,column) has to be changed to a plus

The axis/angle description is caculated to be 19.6° about [0.462,0.418,0.248] (note the change in the second element) which is 3.5° from.

I'd like a third oppinion, before changing the article.
