Observation of the Cyclic Water Hexamer in Solid Parahydrogen

Abstract

We present infrared (IR) absorption spectra of cryogenic parahydrogen solids doped with small water clusters. We observe a sequence of peaks shifted to the red by approx. 15/cm from the absorptions of cyclic water clusters in liquid helium droplets K. Nauta and R.E. Miller Science 287 293(2000); this sequence includes the peak due to the cyclic isomer of the water hexamer: cyc-(H2O)6. We believe this is only the second spectroscopic observation of isolated cyc-(H2O)6, and the first report of the IR spectrum of the isolated cluster in the solid phase.
