This volume covers the new methodological advances in NMR spectroscopy that have been
developed since the publication of the first edition. These include:'indirect …

A simple modification of BIRD pulses, which removes the inversion effect on an X nucleus
and retains a chemical-shift evolution of the heterospin, is proposed. This modification …

A new triterpenoid, 3-oxo-12β-hydroxy-oleanan-28, 13β-olide (1), and six known
triterpenoids 2–7 were isolated from the root bark of Ekebergia capensis, an African …

An investigation into the molluscicidal substituents of field garlic, Allium vineale, has resulted
in the isolation and identification of seven new saponins with up to six sugars. The isolations …

A modification of the recently reported ACCORD-HMBC longrange heteronuclear shift
correlation experiment is described. The new experiment, IMPEACH-MBC (improved …

Seven naphthoquinones and nine anthraquinones were isolated from the roots of Aloe
dawei by chromatographic separation. The purified metabolites were identified by NMR and …

An artifact, as the word is often used in the context of pulse and two-dimensional NMR,“)
refers to an unexpected peak or distortion in the spectrum. In an experimental science, these …

Two diastereomers of a model β-hairpin peptide mimetic were synthesized and studied with
a combination of experimental (NMR, X-ray, CD, MS, IR) and computational methods (Monte …

The structures of two new marine diterpenes, clavudiol A (1) and clavirolide A (2), isolated
from the Pacific soft coral Clavularia viridis collected off the Xisha Islands in the South China …

Four new naphthohydroquinones, named busseihydroquinones A–D (1–4), along with a
known homoprenylated dihydronaphthoquinone (5), were isolated from the CH2Cl2/MeOH …
