Abstract (English)

A major breakthrough in speed and sensitivity of 2D spinnoisedetected NMR is achieved owing to a new acquisition and processing scheme called “double block usage” (DBU) that utilizes each recorded noise block in two independent crosscorrelations. The mixing, evolution, and acquisition periods are repeated headtotail without any recovery delays and wellknown building blocks of multidimensional NMR (constanttime evolution and quadrature detection in the indirect dimension as well as pulsed field gradients) provide further enhancement and artifact suppression. Modified timing of the receiver electronics eliminates spurious random excitation. We achieve a threefold sensitivity increase over the original snHMQC (spinnoisedetected heteronuclear multiple quantum correlation) experiment (K. Chandra etal., J. Phys. Chem. Lett. 2013, 4, 3853) and demonstrate the feasibility of spinnoisedetected longrange correlation.
