Experimental determination of structural motifs of interference-free water undecamer cluster (H₂O)₁₁.

ABSTRACT: Structural characterization of archetypal water clusters is essential for exploring the nature of aqueous hydrogen-bonding interactions that are responsible for the properties of water. While spectroscopic measurement of interference-free neutral water clusters has been proven to be challenging due to the difficulty in size selection, recent studies have successfully measured the infrared spectra of small water clusters (H₂O)_n (n = 2-10). Thus far, experimental evidence for structural motifs of larger water clusters (H₂O)_n (n ≥ 11) without environmental perturbation such as an ultraviolet-chromophore label, a messenger tag, or a host matrix has been lacking. Here utilizing the recently-developed size-specific infrared spectroscopy apparatus with
