Question

Quizplus · Accepted Answer

Delta (δ) is used to represent the relative position of each signal in the NMR spectrum along the chemical shift scale.

Answer: A
 TMS (tetramethylsilane) is used as a reference compound in NMR spectroscopy to calibrate the chemical shift scale.

Answer: C
 The frequency of the NMR signal is measured in megahertz (MHz), which is a unit of frequency.

Answer: E
 The low-field or downfield side of an NMR spectrum refers to signals that appear at higher chemical shifts compared to the reference compound (TMS).

Answer: B
 The high-field or upfield side of an NMR spectrum refers to signals that appear at lower chemical shifts compared to the reference compound (TMS).

Answer: G
 The intensity of an NMR signal represents the relative number of nuclei that give rise to the signal. Intensity is usually represented by the height or area under the peak.
