Chemical dynamics simulations have emerged as a pivotal tool for unravelling the intricate processes underlying ion fragmentation and energy transfer. These computational studies employ ab initio and ...

Collision-activated dissociation (CAD), the most widely used peptide ion fragmentation technique for peptide sequence analysis by tandem mass spectrometry, works great for small peptides but is ...

Since the discovery of the double helix form of DNA and the hypothesis of DNA mutation induced by proton transfer more than 50 years ago, it has been recognized that proton transfer is crucial to many ...

Ion-mobility spectrometry (IMS) separates and characterizes ions in the gas phase based on their mobility within a carrier gas. IMS has recently being coupled with mass spectrometry (MS) and ...
