Both positive and negative plasma desorption mass spectra of the three-dimensionally non-molecular material [ Cd(SC,H,-2-CH3)2] contain fragment ions directly related to the lattice structure of the material. Fragment ions are observed which correspond with [ CdSC,H, I +' and [ CdS,C,H, I -' which d

## Abstract A general approach for the detailed characterization of sodium borohydride‐reduced peptidoglycan fragments (syn. muropeptides), produced by muramidase digestion of the purified sacculus isolated from __Bacillus subtilis__ (vegetative cell form of the wild type and a __dacA__ mutant) and
## Abstract The results from the laser‐ablation Fourier transform mass spectrometric examination of a variety of polyaromatic hydrocarbons (PAHs), coals and other geochemically related materials are presented. Both molecular and quasi‐molecular ions have been detected from different ring‐sized PAHs
