Abstract:
We present an approach that accelerates protein solid-state NMR 5-20-fold using paramagnetic doping to condense data-collection time (to approximately 0.2 s per scan), overcoming a long-standing limitation on slow recycling owing to intrinsic (1)H T(1) longitudinal spin relaxation. Using low-power schemes under magic-angle spinning at 40 kHz, we obtained two-dimensional (13)C-(13)C and (13)C-(15)N solid-state NMR spectra for several to tens of nanomoles of beta-amyloid fibrils and ubiquitin in 1-2 d.

As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...

¹H NMR: Complex Splitting
Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied first.
