Due to this, in presence of magnetic field also, the p-orbitals are three-fold degenerate. In covalent bonding, two atomic orbitals can collaborate to generate two “hybrid orbitals”. The hybrid orbitals have two energy levels.

WebJun 7, 2015 · χ A ( λ) = det ( A − λ I) The eigenvalues are the roots of this polynomial, and the eigenvectors for a given root are just the vectors in the kernel of A − λ I. You should find a factorisation: χ A ( λ) = ( λ + 2) 2 ( 3 − λ), whence the third eigenvalue: λ = 3. The subspace E − 2 has dimension 2, so the matrix is diagonalisable.
