Conclusions and Future Work
In order to develop our understanding of the nature of hydrogen-bonded water networks, we extended the spectroscopic investigation of water clusters to previously inaccessible regions in cluster chemistry. We established a new experimental scheme and developed a new experimental setup, using it to successfully measure size-selective IR spectra of large clusters as well as highly reactive water clusters. Problems in cluster spectroscopy, internal energy and isomer distribution, were addressed with a systematic cooling method. The observed findings have provided us with hitherto unrecognized information on the nature of hydrogen-bonded water networks.
