## Abstract Ionization efficiency curves for [M ο£Ώ X]^β^ ions from __p__βXC~6~H~4~Nο£ΎNC~6~H~5~ molecules (Xο£ΎF, Cl, Br) have been registered in the energy range 0β9 eV with appearance energies 3.3, 4.1 and 3.2 Β± 0.2 eV, respectively. The heats of formation of 17 isomeric C~12~H~9~N^β^ ions have been e
The reactions of o-, m-and p-benzyne anions and the phenide ion with a series of neutral reagents are described. The m-and p-benzyne anions display similar behavior towards acids, NO and , analogous to that of phenide ion but clearly di β erent from that of o-benzyne anion. The strongly basic and nu
The positive ion chemical ionization (CI (isobutane)), negative ion chemical ionization (NICI) electron attachment (CH,,, He) and NICI (OH-) spectra of the title compounds have been studied in detail with the aid of deuterium-labelled derivatives. me obtained results show that under CI conditions th
The mycobacterial O-methyl-D-glucose polysaccharide (MGP) and its acylated derivatives, the O-methyl-D-glucose lipopolysaccharides (MGLP), have been analyzed by fast-atom-bombardment mass spectrometry (F.a.b.m.s.). The molecular-ion peaks for MGP confirmed the degree of polymerization and, in addit
