Definitions:

Nuclear Magnetic Resonance

A spectroscopic technique that exploits the magnetic properties of certain atomic nuclei to determine the physical and chemical properties of atoms or the molecules in which they are contained.

Protons in Dichloromethane

Refers to the hydrogen atoms present in the chemical compound dichloromethane, which is an organochloride solvent.

60 MHz

A frequency measurement often associated with the radio frequency range, but in the context of NMR, refers to the operating frequency of some lower field NMR spectrometers.

100 MHz

A frequency often associated with the operational frequency of certain NMR spectrometers, crucial for inducing transitions between nuclear spin states in proton NMR.
