g elect all the statements that correctly relate the degree of shielding of a nucleus to its chemical shift. Multiple select question. A shielded nucleus will absorb downfield compared to a deshielded nucleus. A shielded nucleus will have a lower chemical shift than a deshielded nucleus. The signal for a shielded nucleus will be farther to the left on an NMR spectrum than the signal for a deshielded nucleus. The signal for a shielded nucleus will be closer to the signal for TMS than the signal for a deshielded nucleus.
