Abstract
I still see you: A new pulse sequence, SHA+, little sensitive to dipolar truncation, allows direct or relayed polarization transfer between 13C atoms, distant by 3.5-9.6 Å, in amyloid fibrils (see picture). SHA+ can also be used in a broadband way with the weak rf-condition of v1vR≈0.2-0.3 which permits the investigation of temperature-sensitive biological systems.
