convertimate Dipole moment

Debye to atomic units

Type a value in D to get it in e·a₀ instantly.

0.7278e·a₀

That's about the same as water. That is a whole electron charge separated by about 38.52 picometers.

What it means

How polar is that?

These are gas-phase molecular dipole moments. In a liquid, neighboring molecules polarize each other and the effective value is larger.

The math

How to convert D to e·a₀

To convert debye to atomic units, multiply by 0.39343.

Example: 1.85 D × 0.39343 = 0.727846 e·a₀.

In the other direction, 1 e·a₀ = 2.54175 D.
