NMR Spectroscopy (HL) part 2/2

What is the role of tetramethylsilane in HNMR spectroscopy?

• It serves as a reference standard.

• It is used to split peaks.

• It acts as a solvent.

• It absorbs radio waves.

In high-resolution HNMR, what causes the splitting of peaks?

• Sample purity

• Chemical shifts

• Spin-spin coupling

• Magnetic field strength

What is a doublet in the context of HNMR spectroscopy?

• A single peak

• Two peaks of equal intensity

• Three peaks of varying intensity

• Four peaks of equal intensity

How many splitting patterns are produced by a neighboring CH2 group?

• Three

• Two

• Four

• One

What should be considered when analyzing HNMR spectra?

• The exact match with data book values

• Interactions between non-adjacent protons

• The color of the sample

• The number of neighboring protons
