Definitions:

Deshielded Proton

A proton in an NMR spectrum that appears at lower field due to its electron cloud being less shielded from external magnetic fields, often indicating an electron-withdrawing group nearby.

Farthest Downfield

In NMR spectroscopy, refers to the signal appearing at the lowest field strength, typically associated with environments experiencing the greatest deshielding.

Signal Intensity

In the context of spectroscopy or imaging, it refers to the magnitude of a detected signal, indicating the presence or concentration of a substance.

Magnetic Field

A vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
