## Abstract The mechanism of the collisionโinduced fragmentation of peracetylated methylโฮฑโDโglucopyranoside was investigated using deuteriumโlabelled acetates and sequential mass spectrometry. Loss of the substituent at C(1), the anomeric carbon, yields an ion of __m/z__ 331, [C~14~H~19~O~9~]^+^.
The probability fos ceILsion4nduced dissociation near the energy threshold, is shown to increase exponentially with the initial vibrational energy of the diatomic molecule, in agreement with the experiment of TuUy et aL At higher collision energies the effect is Eess pronounced and, at sufficiently
The slow, low pressure, unimolecular dissociation reactions of the weakly bound cluster ions, [ (CH3) 2CO] โข CI-, (C6H6) โข C1 and (CH3OCH3) n โข H30 + (n = 2, 3), and their deuterated analogues have been examined by Fourier transform ion cyclotron resonance spectrometry.
