Abstract

Size-dependent development of the hydrogen bond network structure in large-sized clusters of protonated water, H+(H2O) n (n = 4 to 27), was probed by infrared spectroscopy of OH stretches. Spectral changes with cluster size demonstrate that the chain structures at small sizes (n ≲ 10) develop into two-dimensional net structures (∼10 < n < 21), and then into nanometer-scaled cages (n ≥ 21).
