MALDI of Layered Polymer Films

March 1, 2004
Author(s)
Barry J. Bauer, Kathleen M. Flynn, B D. Vogt
A layered preparation method is introduced that produces structured MALDI targets with well-defined phase sizes and compositions. Tri-a-naphthyl benzene is a glassy matrix that forms smooth films. It is layered with polystyrenes or polyethylene glycol

Optimizing the Covalent Cationization Method for the Mass Spectrometry of Polyolefins

August 1, 2002
Author(s)
Sheng Lin-Gibson, L Brunner, David L. VanderHart, Barry J. Bauer, B M. Fanconi, Charles M. Guttman, William E. Wallace
Previously a new method was introduced for the mass spectrometry of polyolefins whereby an organic cation is covalently bonded to the polymer to produce the necessary ionization for the creation of intact gas?phase macromolecules by matrix-assisted laser

Rearrangement of Perfluorocyclobutyne

November 1, 1999
Author(s)
K B. Wiberg, M Marquez, Carlos A. Gonzalez
The energies of cyclobutyne, perfluorocyclobutyne and related compounds have been calculated at levels from MP2/6-31G* through QCISD(T)/6-311+G*, and also at B3LYP and B3PW91/6-311+G*. The relative energies found with the larger basis sets are quite
