We attribute them to the sequential kynurenine fragmentation.
The three most abundant signals of a survey scan (400 1300 m/z range, 0.87 s scan time and 0.13 s inter-delay) were selected by charge state, and collision energy was applied accordingly for sequential MS/MS fragmentation scanning (50 2000 m/z range, 0.9 s scan time, 0.1 s inter-delay).
In general, it thus appears that preferred sequential amino acid fragmentation takes place from the N-terminus up to the linker molecule followed by subsequent internal fragmentation starting at the C-terminus.
Poly(2,2,2-trifluoroethyl acrylate -block-poly(glycidyl methacrylate -block-polyGMacrylate -block-poly was synthesized via sequential reversible addition-fraglycidylon chain transfer (RAFT) polymethacrylate

The tadpole-shaped block copolymer was prepared by sequential reversible addition-fragmentation chain transfer polymerization of styrene (St) and 4-vinylpyridine (4VP) at the presence of chain transfer agent-modified polyhedral oligomeric silsesquioxanes (POSS).
In this contribution, we reported the synthesis of poly vinylidene fluoride -block-poly N-vinylpyrrolidone) (PVDfluoride -block-poly N-vinylpyrrolidoneential reversible addition-fluoride -block-poly N-vinylpyrrolidoneecular design via the interchange ofluoride -block-poly N-vinylpyrrolidone
The sequential reversible addition-fragmentation chain transfer (RAFT) polymerization of these monomers via the R-approach using bi-, tri- and tetrafunctional chain transfer agents (CTAs) bearing hydrophobic dodecyl moieties proceeded in a well-controlled manner up to almost quantitative conversion.
Toward this end, we first synthesized poly N-vinylpyrrolidone -block-poly N-vinylcarbazole -block-poly N-vinyl poly N-vinylpyrrolidone -block-poly N-vinylcarbazole -block-poly N-vinylsible addition-fragmentation chain transfer/macromolecular design via the interchange of xanthate (RAFT/MADIX) poly N-vinylpyrrolidone -block-poly N-vinylcarbazole -block-poly N-vinylain the nanostructured thermosets.
If the book's semi-sequential structure, emphasised by a puzzling abundance of separating blank pages, creates a fragmented quality, fragmentation may be what the poems want to explore.
