cluster species, and studies on rare gas and related van der Waals systems, as well
as those comprised of hydrogen-bonded molecules. Such a book involving both
gas-phase and wet-synthetic metal clusters was initially proposed by Prof. A. W.
Castleman, Jr. who passed away in Feb. 2017. To continue Will’s spirit, now we
have completed the collection of a diverse set of topics in this book and highlight the
stability and reactivity of metal clusters at reduced sizes. There has been a delay and
Will is not there to see its publication. Accordingly, this book is dedicated to him for
his honorable contributions in cluster science. Sincerely, we hope that readers will
find the limited material interesting and helpful, although the present version may
still not cover all aspects of metal clusters and their reactivity.
