In doing so, each imino chemical shift in the lookup table can be split into three components as shown in Table 2: (1) the intrinsic chemical shift of the central base pair; (2) the contribution to the specific central base pair from the 5′ base pair; (3) the contribution to the s...
Chemical Shift Imaging is a technique used in NMR spectroscopy and MRI to identify different molecules and map their distribution within a sample by selectively exciting or suppressing the signal of molecules with specific chemical shifts. AI generated definition based on: Progress in Nuclear Magnetic ...
