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.
