Dr. William Weltner is supported by a grant from The                         Experimental Physical Chemistry Program to investigate the                      physical properties of small clusters of metals,                                semiconductors, carbon and silicon which are trapped in low                     temperature inert gas matrices.  The primary experimental                       techniques used in these studies include optical spectroscopy                   and ESR/ENDOR spectroscopy.                                                                                                                                        A large body of experimental data consisting of spin                         multiplicities, symmetries, optical transitions, vibrational                    frequencies, g-tensor elements, hyperfine splittings,                           zero-field parameters, and exchange coupling constants will be                  used to characterize low temperature matrix isolated clusters                   of the follow types:  1) clusters of transition and rare-earth                  metals, neutrals and ions; 2) clusters of carbon, silicon, and                  silicon carbide, neutrals and ions;  3) ionic clusters of                       inorganic antiferrro- and ferro-magnetic crystals such as                       manganese difluoride;  4) microparticles of noble metals; and                   5) reaction products of small metal clusters with oxygen,                       hydrogen and carbon monixide.                                                                                                                                      An extensive program of ESR and vibrational spectroscopy in                  the far-infrared is proposed to allow the observation of                        transition metal clusters with large zero-field splittings.
