Abstract

Dimethyl ether (DME) chemical ionization mass spectrometry with introduction by direct exposure desorption was utilized for the characterization of a variety of nitramines, nitroaromatics and related compounds. For the nitramines and for many of the nitroaromatics the most abundant ions were fragmentโ€molecule adduct ions resulting from ionโ€molecule reactions with the reagent gas. Nitroaromatic positional isomers were readily distinguished by large differences in the abundances of the various adduct ions. For the nitramines, collisionโ€induced dissociations of the prominent methoxymethylene adduct ions were studied and contrasted with those of the corresponding adducts derived from DMEโ€d~6~ as reagent gas.

## Abstract The chemical ionization mass spectra of the isomeric 2,4โ€adamantanediol diacetates and dimethyl ethers have been determined using methane and isobutane as reagent gases. The significant differences in the spectra of the diacetates allow an unambiguous identification of the isomers. The
