Covering: up to November 2012 Over the past 28 years there have been several thousand
publications describing the use of 2D NMR to identify and characterize natural products …

The relative merits of different pairs of two-dimensional NMR pulse sequences (COSY-90 vs
COSY-45, NOESY vs T-ROESY, HSQC vs HMQC, HMBC vs CIGAR, etc.) are compared and …

Appendix A. Circulant and Toeplitz matrix computations........................................... 293 B.
Glossary..................................................................... 294 B. 1. Basic matrix definitions …

Practical strategies for the structural elucidation of small organic molecules are described for
typical organic chemists. The analysis of an unknown is divided into three stages. First …

The application of a computer‐assisted structure elucidation expert system, CISOC–SES,
leading to the unequivocal 1H, 13C and NOE resonance assignment of betulinic acid, a …

There continues to be a disturbing number of natural products reported in the literature
whose structures are incorrect. At least in part, this reflects the fact that many natural product …

An improved pulse sequence for the 3D DOSY experiment 2DJ-DOSY, using diffusion
encoding internal to the parent 2DJ spectroscopy sequence (2DJ-IDOSY), is presented. The …

Abstract The CRAFT (Complete Reduction to Amplitude Frequency Table) technique, based
on Bayesian analysis approach, converts FID and/or interferogram (time domain) to a …

A new algorithm for optimizing spectral width in the indirect dimension of heteronuclear 2D
experiments is introduced. It takes a list of carbon chemical shifts as input and calculates the …

Four cardenolides were isolated from Calotropis procera. Their structure and conformational
behaviour were investigated by the extensive application of one-and two-dimensional 1H …
