Definitions:

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.

Electronegative Atoms

Atoms with a high ability to attract electrons towards themselves, which affects bond polarity and molecular structure.

Deshielded

A term used in nuclear magnetic resonance (NMR) to describe a nucleus whose electron cloud is perturbed in such a way as to reduce the shielding effect, often leading to an upfield shift in the NMR spectrum.

Dibutyl Ether

An organic compound formed by the dehydration of butanol, used as a solvent and in chemical synthesis.
