1-(+)-Dehydroabietylimidazolium Salts as Enantiomer Discriminators for NMR Spectroscopy

Parallel Translations As Sense Discriminators

This article reports the results of a p r e hmlna ry analysis of translation equivalents in four languages from different language famdles, extracted from an on-hne parallel corpus of George Orwell's Nmeteen Eighty-Four The goal of the study is to determine the degree to which translatmn equivalents for different meamngs of a polysemous word In Enghsh are lexlcahzed differently across a variety...

Salts of Phosphonic Acid Derivatives: Illustrative Examples of Solid State NMR Spectroscopy

High-resolution solid state 13C, 23Na and 31P NM R data have been obtained for the acid form and for several salts o f the phosphonic acids: ethane-1 ,2 -diphosphonic acid, ethane-l-hydroxy1.1-diphosphonic acid (H E D P ), and 3-am ino-l-hydroxypropane-l,l-diphosphonic acid. The data provide evidence by which sample purity and crystallinity may be examined and from which the size of the asymmet...

NMR Spectroscopy in Microfluidic Stripline NMR Chips

Microfluidic stripline NMR technology not only allows for NMR experiments to be performed on small sample volumes in the submicroliter range, but also experiments can easily be performed in continuous flow because of the stripline’s favorable geometry. In this study we demonstrate the possibility of dual-channel operation of a microfluidic stripline NMR setup showing oneand twodimensional H, C ...

RNA nucleosides as chiral sensing agents in NMR spectroscopy.

The study reports chiral sensing properties of RNA nucleosides. Adenosine, guanosine, uridine and cytidine are used as chiral derivatizing agents to differentiate chiral 1°-amines. A three component protocol has been adopted for complexation of nucleosides and amines. The chiral differentiating ability of nucleosides is examined for different amines based on the (1)H NMR chemical shift differen...
