Investigations in metal clusters have importantly become an
open field of basic and applied researches. Small clusters are
declared to show geometrical, electronic, and magnetic properties
that are different from the bulk materials. The geometrical
arrangements of clusters change with size and a profound
properties influenced by size are evolved. Hence,
geometry and size are key factors to new behaviors, though
the difficulty arises with size investigation is that clusters are
too small for usual spectroscopic techniques.[1] In spite of
this, interaction of materials with metal cluster has becoming
a prototype for resolution of scientific concepts in applied
research.
