Abstract 



Two recent experimental studies by Zweiback et al. (Phys. Rev. Lett. 84, 2634 (2000)] and by Gobet et al. [Phys. Rev. Lett. 89, 183403 (2002)) have motivated us to study the groundstate geometry and the consequent electronic structure of the singlycharged cationic hydrogen cluster H3(+)(H2)(m) for m=2,5 and 14, using at first the HartreeFock approximation. For the H7(+) cluster the fully optimized groundstate geometry yields an isosceles triangle H3, with charge similar to 0.85\e\, and sides 0.852 and 0.884 Angstrom, flanked by two H2 molecules lying parallel to each other, with bond lengths of 0.740 Angstrom. In contrast, for the H13(+) cluster, the central 'building block' is equilateral H3 with bond length 0.861 Angstrom, and with charge similar to 0.815\e\. This configuration of H3 is flanked by three almostparallel H2 molecules with bond length 0.739 Angstrom. MP2 refinements of geometry, charge distribution and normal mode vibrational frequencies of the cationic tritium cluster T7(+) and the corresponding deuterium cluster D13(+) are also reported. Finally, HartreeFock and MP2 results are recorded for H31(+).
