They mimic electronic shell structures of atoms and are called structurally defined superatoms. The book describes the design principle of superatomic electronic structures and the bonding theory of superatoms as revealed by gas-phase anion photoelectron spectroscopy, which is conducted by using a state-of-the-art home-built apparatus and sheds light on fundamental electronic structures such as density of states and electron affinities otherwise elusive. This study revealed that the energy level of superatomic orbitals can be tuned coarsely by the heterometal doping and finely by the stepwise ligand exchange, respectively. The bonding theory of superatoms was also developed by anion photoelectron spectroscopy of homonuclear and heteronuclear superatoms. The comprehensive review of superatoms and detailed explanation of the apparatus were described in addition to individual studies. This book provides design principles of structurally defined superatoms and stimulates future research on the chemical and physical properties of superatoms. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5061 606 $aNanochemistry 606 $aSpectrum analysis 606 $aDensity functionals 606 $aNanoparticles 606 $aNanochemistry 606 $aSpectroscopy 606 $aDensity Functional Theory 606 $aNanoparticles 615 0$aNanochemistry. 615 0$aSpectrum analysis. 615 0$aDensity functionals. 615 0$aNanoparticles. 615 14$aNanochemistry. 615 24$aSpectroscopy. 615 24$aDensity Functional Theory. 615 24$aNanoparticles. 676 $a541.2 700 $aIto$b Shun$4aut$4http://id.loc.gov/vocabulary/relators/aut$01802920 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910987785903321 996 $aElectronic Structures and Bonding Interaction of Structurally Defined Gold$94349294 997 $aUNINA
