How it works
Biological Formula Standard
An electric dipole consists of two equal and opposite charges separated by a distance d. The dipole moment p = qd points from negative to positive charge. It determines the torque on the dipole in an external field and the field produced by the dipole at large distances.
Frequently Asked Questions
What is a Debye?
1 Debye = 3.336 × 10⁻³⁰ C·m. It's the standard unit for molecular dipole moments. Water has p ≈ 1.85 D. HCl ≈ 1.08 D. CO₂ = 0 D (symmetric).
Why do molecules have dipole moments?
Unequal sharing of electrons in bonds creates partial charges. Polar molecules (water, HCl) have net dipole moments. Symmetric molecules (CO₂, CH₄) can have polar bonds but zero net dipole moment.
How does a dipole interact with a field?
Torque τ = p × E tends to align the dipole with the field. Energy U = -p·E is minimized when aligned. This is the basis of dielectric behavior, microwave heating, and NMR.

How to Avoid Critical Calculation Mistakes
Even when using high-fidelity dynamic models, analytical mistakes can creep into standard computations. To safeguard results, keep these common errors in mind:
