A first-order saddle point is a position on the PES corresponding to a minimum in all directions except one; a second-order saddle point is a minimum in all directions except two, and so on. Defined mathematically, an nth order saddle point is characterized by the following: ∂E/∂r = 0 and the Hessian matrix, ∂∂E/∂ri∂rj, has exactly n negative eigenvalues.
