I know that if I have a symmetrical matrix defined on $R$, it is always diagonalisable and I can always find beetwen the matrix of its eigenspaces an orthogonal matrix. While if I have a non diagonalisable matrix, of course I can put it in Jordan normal form, however how the matrix must be to be able to find out an orthogonal matrix of its generalized eigenvectors?

When is possible to use an orthogonal matrix to put in Jordan form a matrix?
