Abstract
^13^C chemical shifts and ^13^C^205^Tl spin–spin coupling constants are reported for phenylthallium(III) bis(trifluoroacetate) and some of its mono‐ and dimethyl derivatives. The signs of ^n^J(^13^C, ^205^Tl) relative to ^n+1^J(^1^H, ^205^Tl) are determined by offresonance decoupling of protons.

## Abstract The ^13^C NMR spectra were determined and signals assigned to the various carbons of the alkamines veracevine, germine and zygacine derived from steroidal alkaloids of the ceveratrum class. Assignment of signals was aided by analysis of the partially relaxed spectrum of cervagenine 9,12
## Abstract The PMR spectra of the titled carbanion have been observed well‐resolved and suitable for first‐order analysis. Excess charges localized in the phenyl rings are estimated from the chemical shifts and compared with those observed in other carbanions.
