Question

Precession of the nucleus can lead to a free induction decay observed in this technique. For 10 points each:
[10e] Name this form of spectroscopy that is frequently applied to hydrogen-1 nuclei. It uses a strong magnetic field to probe a sample immersed in solvent.
ANSWER: NMR spectroscopy [or nuclear magnetic resonance spectroscopy]
[10m] The results of NMR can be measured with this quantity, equal to the sample’s resonant frequency minus solvent frequency over solvent frequency. TMS is defined as having a value of zero for this quantity.
ANSWER: chemical shift
[10h] In NMR, the constants T-1 and T-2 quantify the time it takes for nuclei to go through this process, where their magnetization returns to its initial value. This process comes in spin-lattice and spin-spin types.
ANSWER: relaxation [accept relaxation time]
