WebIf you use Gaussian, you can use Opt= modredundant and then Fix the variables (distances, angles, or dihedrlas) of the selected atoms WebGaussian includes the STQN method for locating transition structures. This method, implemented by H. B. Schlegel and coworkers [Peng93, Peng96], uses a quadratic synchronous transit approach to get closer to the quadratic region of the transition state and then uses a quasi-Newton or eigenvector-following algorithm to complete the optimization.
