TOP-PASS: A processing algorithm to reduce 2D PASS acquisition time

► We demonstrate a new processing algorithm for 2D PASS. ► We utilize a double shear transformation to correlate a high speed MAS dimension to a broad anisotropic dimension. ► We demonstrate how processing 2D PASS spectra as a TOP dataset can significantly reduce experiment time when the isotropic spectral width is narrower than the anisotropic spectral width. ► This approach is demonstrated on 2D PASS spectra of 29Si in Clinoenstatite and 13C in l-Histidine. ► The new processing approach is termed TOP-PASS.
