Natural products and their derivatives have historically been invaluable as a source of
therapeutic agents. However, in the past decade, research into natural products in the …

The 13 C NMR chemical shifts of 130 naturally occurring steroidal sapogenins and saponin
derivatives published up to 1983 are listed and a number of methods for signal assignment …

A novel concept in vibrational spectroscopy called two-dimensional infrared (2D IR)
spectroscopy is described. In 2D IR, a spectrum defined by two independent wavenumbers …

This book is about pulse nuclear magnetic resonance (NMR), with its techniques, the
information to be obtained, and practical advice on performing experiments. The emphasis …

A method is described for obtaining pure absorption phase spectra in four quadrants in a
two-dimensional nuclear magnetic resonance spin exchange experiment. It is shown that …

Techniques for the correlation of 1 H and 15 N chemical shifts based on zero and double
quantum NMR are discussed. The indirect determination of nitrogen shifts from the proton …

Proton-proton couplings in a sample of 9-hydroxytricyclodecan-2, 5-dione were studied by
the two-dimensional Fourier transform method proposed by Jeener. Various techniques …

The solution properties of zwitterionic surfactants are shown to be strong functions of the
type of negatively charged center (carboxylate vs sulfonate) and the number of methylene …

A general scheme is proposed for the determination of spatial protein structures by proton
nuclear magnetic resonance. The scheme relies on experimental observation by two …

Available in paperback for the first time, this book describes the main methods of one-and
two-dimensional high-resolution NMR spectroscopy in liquids within the quantum …
