See here for the corresponding statement about complex skew-symmetric matrices using unitary matrices instead of orthogonal ones. Note that the blocks in the matrix $\Sigma$ at this link are themselves diagonalizable, so $\Sigma$ is diagonalizable.

Matrix A can be further divided into two ma-trices A = E + G , where E is diagonal and describes the static part of the diabatic eigenvalues of H (t) and the level couplings are included in matrix G . Non-Hermiticity is introduced into H (t) via the coupling matrix G , which satis es the anti-Hermitian condition, G y = G . Anti-
