  • A laser ionization source has been developed and applied to measure the equilibrium thermochemistry of the clustering of neutral molecules with atomic metal ions. This high-pressure mass spectrometric method enables cluster association reactions to be studied at pressures that ensure both atomic ion thermalization and collisional stabilization of the nascent cluster ions. Initial application to the thermochemical properties of the association reactions of Cu{sup +} with Kr, N{sub 2} (up to five molecules), H{sub 2}O, CH{sub 3}OH, and CH{sub 3}COCH{sub 3} is described. The binding energies for Cu{sup +}{center dot}Kr and Cu{sup +}{center dot}N{sub 2} are similar to the analogousmore » Na{sup +} complexes, as expected from predominantly electrostatic interactions. The binding energies show reasonable variations with the proton affinity of the molecule.« less
  • Archaeologists have considerable interests in ancient bronzes. They want to know how these alloys were produced and how they corroded with time. Modern bronzes, with compositions very close to that of some ancient bronzes, have been produced and two methods were examined to characterize one of these modern bronzes. Analysis of this modern bronze using resonance enhanced multiphoton ionization/secondary neutral mass spectrometry (REMPI/SNMS) is examined in detail and compared to cesium attachment secondary ion mass spectrometry (CsAMS) results. Both REMPI/SNMS and CsAMS were used to quantify the composition of Fe, Ni and Mn in a modern quaternary bronze designed tomore » serve as a certified reference material for an ancient bronze. Both methods exhibit reduced matrix effects when compared to secondary ion mass spectrometry (SIMS) and thus quantification should be simplified. It was found that when relative sensitivity factors obtained from a standard bronze material are used to calibrate the instruments, the REMPI/SNMS measurements yield results that were more sensitive and more accurate.« less
  • The development of the Nier spectrometer from a glass lab-type instrument to the present practical, rugged versatile device is described. The instrument now used is completely automatic, easily operated and serviced, and is adaptable for remote control. (T.R.H.)
