Abstract

CCSD(T)/aug-cc-pVQZ and CCSD(T)/aug-cc-pV5Z methods have been employed to obtain accurate interatomic potentials for Li+e, from which spectroscopic parameters are derived. A potential is presented using the larger basis set consisting of 91 points (R⩾1.3 Å). An accurate value for the long-range D4 parameter could be obtained from the potential, but it was not possible to extract higher Dn terms. Since accurate values for Dn (n=4, 6, 7 and 8) could be derived from literature data, these parameters were fixed (and damped), allowing the short-range potential to be fitted accurately to a Born–Mayer potential.

Item Type:	Article
Additional Information:	JM directed the theoretical studies in collaboration with spectrosopists then at Sussex (TGW) and co authored the paper. The paper probes the nature of the interatomic potential and how many ro-vibronic levels are sustained, important for understanding the transport properties of cations in inert gases.
