## Abstract The ring current and local anisotropic contributions to the ^1^H chemical shifts of [__n__]annuleno[__m__]annulenes and [__n__]annulenyl[__m__]annulenes with __n__, __m__ = 12, 14, 18 and __n__, __m__ = 13, 15 are calculated. The agreement between experimental and calculated shifts for
A 220 MHz NMR spectrometer has been used to identify the structure of polychlorinated biphenyls (PCBs). The proton chemical shifts and approximate coupling constants of PCBs fractionated from Aroclor 1254 are given in the text. The spectra of model compounds are included in the supplement. The chemi
