Sustained off-resonance irradiation for collision-activated dissociation involving Fourier transform mass spectrometry. Collision-activated dissociation technique that emulates infrared multiphoton dissociation
TL;DR: In this article, a collision-activated dissociation (CAD) involving Fourier transform mass spectrometry (FTMS) is described, which can also be effected by application of a sustained (⩾ 500 ms) off-resonance (SORI) electric field pulse.

The gas‐phase basicities and proton affinities of amino acids and peptides
TL;DR: The methods of establishing gas-phase basicities and proton affinities are reviewed in this paper, particularly as applied to thermally labile and involatile molecules, and inconsistencies in the experimental results are discussed.

Inelastic Collisions of Fast Charged Particles with Atoms and Molecules-The Bethe Theory Revisited
TL;DR: In this article, the Bethe theory has been updated with a number of new developments which need to be included in that body of material, such as the ${z}^{3}$ effect and the stopping power for particles at extreme relativistic energies.

Ion-Polar molecule collisions: the effect of ion size on ion-polar molecule rate constants; the parameterization of the average-dipole-orientation theory
Timothy Su,Michael T. Bowers +1 more
TL;DR: In this paper, the average-dipole-orientation theory has been parameterized to permit determination of capture limit rate constants by reading a graph and making a simple calculation, and a graph covering the range of polarizabilities and dipole moments of most molecules is included.
