BaBa-xy16: Robust and broadband homonuclear DQ recoupling for applications in rigid and soft solids up to the highest MAS frequencies

►An improved and truly broadband, supercycled variant of the popular DQ MAS experiment BaBa is introduced. ► The sequence is exceptionally robust and tolerant to large CSA and offsets, with improving performance under ultra-fast MAS. ► We demonstrate the site-resolved determination of weak RDCs and their distributions in anisotropically mobile polymer systems.
