Dihydroxybenzenes give rise to anion radical adduct ions with 3-nitrobenzyl alcohol in addition to the deprotonated adduct ions under fast atom bombardment. 2-Nitrophenyl octyl ether gives only radical anion adducts, whereas other common matrices give deprotonated adducts.

## Abstract Under fast atom bombardment, dihydroxybenzenes form predominantly the M^+·^ and [M + Matrix]^+·^ ions. The second field‐free region metastable decomposition of the [M + Matrix]^+·^ ion involves the loss of a neutral molecule of the matrix. In the case of the hydroquinone–matrix adduct i
The formation of molecular ions, M", under fast atom bombardment (FAB) conditions using a liquid matrix was examined by using a new type of synthesized compounds in which preferential M" peaks appear in their FAB spectra. The FAB spectra were compared with the corresponding mass spectra obtained by
## Abstract The fast atom bombardment (FAB), frit‐FAB and electrospray ionization mass spectra of bis‐ammonium salts, C^2+^ 2X^−^, were compared. The most informative spectra were the FAB mass spectra with __m__‐nitrobenzyl alcohol as matrix and the Frit‐FAB mass spectra. The nucleophilic character
