A comprehensive collection of 13C chemical shifts of 159 tri-and tetracyclic quinolizidine alkaloids (sparteine derivatives) is presented. The data are discussed in terms of substituent e โ ects, molecular geometries and protonation e โ ects. Some IR, 1H and 15N NMR and MS data are included.

## Abstract The ^1^H and ^13^C NMR spectra of the pyrrolizidine alkaloid 13โ__O__โacetyldicrotaline were studied at 4.7 T. A full assignment of the ^1^H and ^13^C signals was achieved by application of a variety of NMR techniques, including homonuclear ^1^H NOE difference, 2D ฮด~H~/ฮด~H~ phaseโsensit
Four small type I collagen CNBr peptides containing complete natural sequences were purified from bovine skin and investigated by CD and 1H- and 13C-nmr spectroscopies to obtain information concerning their conformation and thermal stability. CD showed that a triple helix was formed at 10 degrees C
