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 <221>.

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