Ion cyclotron resonance studies of endothermic reactions of UF−6 generated by surface ionization

Composition of explosives by electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry.

Commercial explosives are complex mixtures that contain not only the active explosive agent(s) but also a host of other organic and inorganic compounds. The ultrahigh mass resolving power (m/delta m50% >200,000) and mass accuracy (<1 ppm) of electrospray ionization Fourier transform ion cyclotron resonance (ESI FTICR) mass spectrometry allow for definitive identification of various species in T...

Melittin Diacylphosphatidylcholine Interaction Examined by Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

The structure of melittin in the presence of dioleoylphosphatidylcholine (DOPC) was investigated using hydrogen deuterium (H/D) exchange in conjunction with collision induced dissociation (CID) in an rf-only hexapole ion guide with electrospray ionization-Fourier transform ion cyclotron resonance mass spectrometry (ESI-FT-ICR MS). The deuterium incorporation into backbone amide hydrogens of mel...

In Ion-cyclotron Resonance Heating

We determine the conditions under which the damping of the fast Alfven wave, used in the heating of tokamak plasmas, can be described by the geometrical optics approximations. Also, for these conditions, we derive an analytical formula which explicitly determines the amount of energy which is damped onto the plasma particles by the fast wave. The conditions for the validity of the geometrical o...
