C-13-detected H-1-H-2 separated local field NMR spectroscopy

Dvinskikh SV, Sandstrom D, Zimmermann H, Maliniak A

We present a new NMR method for measuring H-1-H-2 dipolar couplings in macroscopically oriented media. To overcome the lack of dipolar resolution in 1D H-1 and H-2 spectra of deuterated molecules, we use a 2D heteronuclear correlation experiment where H-1 chemical shifts and H-1-H-2 dipolar interactions in the first dimension are. correlated with C-13 chemical shifts and H-2-C-13 dipolar interactions in the second dimension. The technique is demonstrated on a columnar liquid-crystalline phase. (C) 2003 Elsevier B.V. All rights reserved.
