Toeplitz matrices within discrete variable representation formulation: Application to collinear reactive scattering problems

Recently, a new approach based on the features of the Toeplitz matrix was introduced for reactive scattering problems. So far these features were used only along the reagents translational coordinate (either for Eckart-type models or for collinear scattering). In this work, we show how to employ the Toeplitz features for the two asymptotic regions of the collinear system.
