The 13C chemical shifts of nine 2-X-substituted phenetol derivatives were measured together with the 13C chemical shifts of the corresponding X-monosubstituted benzenes. Using an additivity scheme, the ethoxy cisand transortho-SCSs (substituent chemical shifts) at C-6 and C-2, respectively, were det

Aromatic I3C chemical shifts are reported for a number of ortho-substituted anisoles. Quantitative determination of the substituent chemical shift (SCS) effects of the methoxy group with a fixed coplanar conformation on aryl carbon nuclei was achieved using experimental and theoretical methods.

## Abstract The synthesis and assignment of ^15^N and ^13^C NMR signals of the isoxazole ring in a series of __para__‐substituted 3‐phenyl derivatives are reported. DFT calculations of ^15^N and ^13^C chemical shifts are presented and compared to observed values. Substituent effects are interpreted

## Abstract Indoloquinoline alkaloids represent an important class of antimalarial, antibacterial and antiviral compounds. They have been shown to bind to DNA via intercalation preferentially at GC‐rich sequences containing nonalternating CC sites. The stability of complexes formed with biological
