Infrared laser spectroscopy has been used to characterize the solvation of HCl with small number of water molecules in helium nanodroplets. Complexes of (HCl)m(H2O)n with m = 1 -- 3 and n = 1 -- 3 have been identified in the free OH stretching and bonded OH spectral range of 3000 -- 3900 cm-1. The assignment of the infrared vibrational bands of the clusters is aided by pick-up pressure dependence experiments and ab initio calculations.
