Abstract
Liquid secondary ion mass spectrometry (LβSIMS) of six new functionalized macrocycles was investigated. All six compounds yielded abundant fragment ions and protonation molecular ions [M + H]^+^ under LβSIMS conditions. The proposed fragmentation mechanisms were supported by highβresolution accurate mass data from Fourier transform ion cyclotron resonance mass spectrometric and MS^n^ experiments on using sustained offβresonance irradiation collisionβinduced dissociation.

An efficient technique for generation of H\* (D\*) radicals in Fourier transform ion cyclotron resonance (FTICR) mass spectrometry is described. The method allows the probing of the reactivity of gas-phase H\* radicals towards various ions isolated in the cell of an FTICR mass spectrometer. Results
## Abstract The application of Fourier transform ion cyclotron resonance (FTICR) mass spectrometry to the quantitative study of molecular recognition in the gas phase is reviewed. Because most quantitative measurements are dependent on accurate determination of the pressure of a neutral reagent, me

Several forms of diacetyl-reducing enzyme were found to exist in the human liver cytosol. Three (DAR-2, DAR-5, and DAR-7) of them were purified as a single band on SDS-PAGE by a combination of a few kinds of column chromatographies. The in-gel tryptic digests of the purified enzymes were analyzed by
