The concept of molecular potential is a key in the study of molecular interactions. On page 2986 Eugene Kryachko focuses on the class of so-called “spiked potentials,” obtained by a combination of the harmonic oscillator and a singular potential. Spiked potentials were believed to be impossible to treat within the framework of traditional perturbation theory, however, this work analytically challenges the established knowledge that perturbation theory is not applicable to this type of potential.
