Adiabatic pseudospectral methods for multidimensional vibrational potentials
TL;DR: A new algorithm for computing eigenvalues, spectral intensities, and selected eigenvectors of multidimensional vibrational potential surfaces is described, which demonstrates a very large reduction in computational effort as compared to discrete variable representation (DVR)/adiabatic reduction or standard collocation approaches.

Vector parametrization of the N-atom problem in quantum mechanics. II. Coupled-angular-momentum spectral representations for four-atom systems
TL;DR: In this article, the geometrical description of a four-atom molecular system by three Jacobi relative position vectors is shown to result in matrices representing the kinetic energy operator, prediagonalized to a very large extent.

Quantum-mechanical description of rigidly or adiabatically constrained molecular systems
Fabien Gatti,Yves Justum,Michel Menou,André Nauts,André Nauts,Xavier Chapuisat,Xavier Chapuisat +6 more
TL;DR: In this paper, Menou and Chapuisat generalized this approach to the case of adiabatic constraints, i.e., the variations of certain internal degrees of freedom are adjusted to those of other degree of freedom.

A finite basis‐discrete variable representation calculation of vibrational levels of planar acetylene
TL;DR: In this paper, a methodology for the calculation of high energy vibrational eigenstates of S0 acetylene is described, where the discrete variable representation (DVR) is employed for radial coordinates with a finite basis representation (FBR) for angular coordinates.

Labeling the HCN vibrational states in the regular spectrum
Michel Menou,Claude Leforestier +1 more
TL;DR: In this article, a simplified procedure to assign quantum numbers to a calculated vibrational spectrum is presented, which only requires the computation of the diagonal matrix elements of the position operators between these states.
