Negative ion mass spectra of nido carboranes
Autor: Thomas Onak, Costello L. Brown, Kenneth P. Gross
Publikováno v: Journal of the American Chemical Society. 94:8055-8059
The negative ion mass spectra of 2,3-dicarbahexaborane(8), 2-methyl-nido-2,3-dicarbahexaborane(8) and 2,3-dimethylnido-2,3-dicarbahexaborane(8) have been investigated. Evidence has been found to show that formation of negative ions in these nido carb

Gas phase carboxylate anions fron p-nitrobenzyl esters of fatty acids
Autor: Carcy L. Chan, Costello L. Brown
Publikováno v: Biomedical mass spectrometry. 5(6)
Gas phase carboxylate anions have been efficiently generated from the p-nitrobenzyl esters of nine fatty acids ranging in size from C6 to C22. The process involves the dissociative resonance capture of 2.9 e V electrons by the derivatives. The proced
