✦ Synopsis

The natural abundance 13C-NMR spectra of five alpha-adrenergic blocking agents, tolazoline, dibenamine, azapetine, phenoxybenzamine, and phentolamine, are reported. The chemical shifts of various carbon resonances were assigned on the basis of chemical shift theory, multiplicities observed in single-frequency off-resonance-decoupled spectra, relaxation times, and comparisons with the chemical shifts of model compounds.

## Abstract ^13^C NMR chemical shifts and ^13^C–^19^F and ^13^C–^1^H coupling constants are reported for 103 halocarbons. Methods used for analyzing complex spectra (e.g. simultaneous ^1^H and ^19^F broadband decoupling, 2D INADEQUATE/FRED, HMQC, 35,37Cl isotope effects) are briefly illustrated. Lo
