“…To study the spectroscopic and dynamic properties of a heterotrimer system such as Ne–Li 2 + , it is necessary to construct the potential energy surface (PES), which describes the interactions within the molecular system. In the past decade, extensive research both experimentally and theoretically has been performed to determine the ground-state PES of the Rg–M 2 + vdW complexes. − …”

Theoretical studies of the potential energy surface and vibrational bound states calculations were performed for the ground state of the Ne–Li2 +(X 2Σg +) van der Waals (vdW) complex. The intermolecular interactions were investigated by using an accurate monoconfigurational RCCSD(T) method and large basis sets (aug-cc-pVnZ, n = T, Q, 5), extrapolated to the complete basis set (CBS) limit. In turn, the obtained raw data from RCCSD(T)/CBS(Q5) calculations were numerically interpolated using the Morse + vdW model and the Reproducing Kernel Hilbert Space (RKHS) polynomial method to generate analytic expressions for the 2D-PES. The RKHS interpolated PES was then used to assess the bound states of the Ne–Li2 +(X 2Σg +) system through nuclear quantum calculations. By studying the aspect of the potential energy surface, the analysis sheds light on the behavior of the Ne–Li2 +(X 2Σg +) complex and its interactions between repulsive and attractive forces with other particles. By examining the vibrational states and wave functions of the system, the researchers were able to gain a better understanding of the behavior of the Ne–Li2 +(X 2Σg +) complex. The calculated radial and angular distributions for all even and odd symmetries are discussed in detail. We observe that the radial distributions exhibit a more complicated nodal structure, representing stretching vibrational behavior in the neon atom along its radial coordinate. For the highest bound states, the situation is very different, and the energies surpass the angular barrier.
