The main fragmentation routes of eighteen title compounds and of three 5-chloro derivatives have been investigated with the aid of linked scan (B/E = constant) spectrometry, accurate mass measurements and deuterium labelling.
## Abstract ^13^C NMR chemical shifts have been calculated for structures of some substituted 3βanilinoβ2βnitrobenzoβ[__b__]thiophenes (**2**__o__) and 2βanilinoβ3βnitrobenzo[__b__]thiophenes (**3**__o__) derivatives containing OH, NH~2~, OMe, Me, Et, H, F, Cl and Br. The molecular structures were
## Abstract The ^13^C NMR chemical shift values of (aryl)(2βnitrobenzo[__b__]thiophenβ3βyl)amines were measured in DMSOβ__d__~6~ solutions, suggesting the occurrence of an alternate charge polarization at Cβ3, Cβ2, Cβ3a, Cβ7a, Cβ4 and Cβ5. A dual substituent parameter analysis of the experimental d
