One-dimensional quantum description of the bending vibrations of HCN/CNH for high values of the total angular momentum.

For high values of the quantum number of the total angular momentum J (up to J = 20), quantum mechanical eigenstates (eigenvalues and eigenfunctions) are calculated by the method of Gatti et al. (J. Mol.
