用红外光谱法研究了质子化水分子团簇H+（H2O）（n）（n = 4 ~ 27）中氢键网络结构随团簇尺寸的变化.光谱随团簇尺寸的变化表明，小尺寸（n小于或接近10）的链结构发展为二维网状结构（类似于10 < n < 21），然后发展为纳米尺度的笼状结构（n大于或等于21）。
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 less than or similar to 10) develop into two-dimensional net structures ( similar to 10 < n < 21), and then into nanometer-scaled cages ( n greater than or equal to 21).
