本文报道了低温仲氢固体掺杂小团簇的红外吸收光谱。我们在液氦液滴中观察到了一系列的峰，这些峰从环状水团簇的吸收向红移了大约15 cm（-1）。Nauta和R. E.米勒，Science 287，293（2000）];该序列包括由于水六聚体的环状异构体：cyc-（H2O）（6）产生的峰。我们相信这只是第二个光谱观察到的孤立的cyc-（H2O）（6），和第一个报告的红外光谱的孤立集团在固相。(C)2001年美国物理学会。
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 approximate to 15 cm(-1) 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.
