The cluster beam technique offers promise of becoming a useful tool for chemists in their search for new compounds. Using this technique elemental vapors can be made to react under controlled conditions to form units of condensed matter (clusters) small en ...
A mol. beam mass spectrometer was constructed to study the formation of van der Waals clusters over a wide mass range. Using this app. (SF6)m was detected with 1 ? m ? 100 in the adiabatic expansion of SF6. By irradiating the SF6 jet with a continuous-wave ...
Predissocn. spectra were detd. for SF6-Ar clusters in a mol. beam by monitoring the decrease in a specific mass spectrometer signals induced by a tunable continuous-wave CO2 laser. A red shift occurs downstream from the nozzle as the gas expands and the cl ...
Two-dimensional Fourier transform (2D FT) spectroscopy was applied to ion-cyclotron resonance (ICR) to obtain direct evidence for mass transfer due to ion-mol. collisions. The 2D FT ICR expt., which is closely analogous to 2D exchange NMR spectroscopy (NOE ...
The accumulation of oxygen at GaAs/AlGaAs interfacesgrown by molecular beam epitaxy has been established by secondary ion mass spectrometry profiling of GaAs/AlGaAs multilayerstructures. An enhanced oxygen peak was observed at the boundary between GaAs and ...
The bacterial type VI secretion system (T6SS) is a macromolecular machine that injects effectors into prokaryotic and eukaryotic cells. The mode of action of the T6SS is similar to contractile phages: the contraction of a sheath structure pushes a tube top ...
