Cross-ring fragmentation

GMF excels at distinguishing between stmctural isomers, as match information from a search can be important in identifying diagnostic ions that support one stmcture over another. Important diagnostic ions are often related to cross-ring fragmentation, which will yield information related to the linkages on a stmcture. [Pg.2236]

Cross ring fragmentation, X (A), is labeled by bond number clockwise from the ring oxygen with the first bond being 0. [Pg.193]

None Negative HCID Cross-ring fragmentation (A/X)... [Pg.194]

The sequence of an underivatized hetero-CHO can be deduced from the occurrence of °4A and 4A cross-ring fragments in MS of the pseudomolecular ion as well as MS of sodiated C-type ions (unpublished results from this laboratory). In this case, the sodium ion may be understood as a tag, which allows identification of the reducing end sugar. [Pg.140]
