Scientific paper

Quantum-mechanical calculations at the (SCF + CI) level are presented for the geometries, dipole moments and formation reactions of the two pairs of ions HOSi(+) - HSiO(+) - HSSi(+) - HSiS(+). The only stable isomer with a reasonable chance of being detected in interstellar space through its rotation spectrum is HSSi(+): this ion has a large dipole moment and a bent structure.
