Abstract


The Liversidge Research Lecture, delivered before the Royal Society of New South Wales, 19th June., 1980. Reproduced by permission of the Royal Society of New South Wales from J. Proc. Roy. Soc. N.S.W., 1980, 113, 69-80.

"13C nmr spectroscopy is now extensively used in both synthetic and biological polymer studies. Structural and dynamic properties of a polymer can be determined from the 13C nmr chemical shift and relaxation time parameters. Examples from both the synthetic and biological fields are presented together with descriptions of new techniques for the analysis of end groups and the determination of tacticity in synthetic polymers."
