TLDR
The structures of three complex saponins from the fruit pods of Blighia sapida have been elucidated and their (1)H and (13)C NMR spectra assigned employing a variety of one- and two-dimensional NMR techniques without degradative chemistry.About:

NMRPipe: a multidimensional spectral processing system based on UNIX pipes
TL;DR: The asynchronous pipeline scheme provides other substantial advantages, including high flexibility, favorable processing speeds, choice of both all-in-memory and disk-bound processing, easy adaptation to different data formats, simpler software development and maintenance, and the ability to distribute processing tasks on multi-CPU computers and computer networks.

Iterative schemes for bilinear operators; application to spin decoupling
TL;DR: A new series of broadband heteronuclear decoupling sequences, called the DIPSI sequences, which give better quality decouplings of protons from carbon-13 than previous sequences like WALTZ-16 when there is scalar coupling among the protons.
