## Abstract Fast‐atom‐bombardment (FAB) mass spectra have been used to establish or confirm the nature of the yellow‐product and open‐chain forms of thiamine produced in the presence of excess (5 mol‐equivb.) of strong base. Time‐dependent changes in ^1^H‐NMR spectra show that the rates of disappea

## Abstract The spontaneous or collision‐induced unimolecular dissociations of base‐protonated 2′‐deoxyribonucleosides afford, in the gas phase and in the absence of solvent, high yields of protonated nucleobases. The release of neutral bases corresponds to a high‐energy reaction path and does not
Fast-atom bombardment (FAB) mass spectrometry was used to investigate the interaction of proton and alkali metal ions with dinucleotide analogs such as T-n-T (T = thymine moiety, n = polyether chain, e.g., triethylene, tetraethylene, pentaethylene, and hexaethylene ether l-4), A-n-T (A = adenine uni
A fast atom bombardment mass spectrometric study of the meso-substituent effect of octaethylporphyrins (QEPX, X = NH, , CH, , H, CHQ, C1, CN, NO,) is reported. The intensity of the [ M + H] + ion peaks was estimated quantitatively using an external standard, which was observed to be correlated linea
