Abstract

I still see you: a new pulse sequence, SHA+, little sensitive to dipolar truncation, allows direct or relayed polarization transfer between (13)C atoms, distant by 3.5-9.6 Å, in amyloid fibrils. SHA+ can also be used in a broadband way with the weak rf-condition of ν(1)/ν(R)≈0.2-0.3 which permits the investigation of temperature-sensitive biological systems.
