Peter Debye

1884–1966 · Netherlands, United States · Born in the 1800s

Nobel Chemistry 1936

Dutch-American physical chemist who laid the experimental and theoretical foundations of molecular structure determination, electrolyte theory and X-ray diffraction.

Nobel Prize work

Showed how dipole moments and the diffraction of X-rays and electrons in gases reveal molecular structure. His Debye-Scherrer powder diffraction method and the unit named for the dipole moment became standard tools for determining bond lengths and polar character.

Ionic, covalent and metallic bonding

Compare ionic attraction, shared electron pairs and delocalised metallic electrons. Bonding models explain why solids conduct, melt or fracture differently.

Electrolytes, pH, buffer solutions

How dissolved ions conduct electricity, how acid–base equilibria set pH, and how conjugate pairs resist pH change in a buffer.

Crystal structures, X-ray diffraction

A crystal is periodic order on the atomic scale. X-rays scattered by that periodic array interfere constructively only in specific directions, turning a diffraction pattern into evidence about the unit cell and atomic arrangement.
