HOMO-LUMO Energy Gap Calculator

HOMO-LUMO Energy Gap Calculator ⚛️

Energy Gap: 0 eV

What is the HOMO-LUMO Energy Gap? 🔬

In molecular orbital theory, the **HOMO (Highest Occupied Molecular Orbital)** and **LUMO (Lowest Unoccupied Molecular Orbital)** define a molecule’s electronic properties. The energy difference between these orbitals is crucial in quantum chemistry and DFT calculations.

How to Calculate HOMO-LUMO Gap Using NWChem ⚛️

To compute the **HOMO-LUMO gap** using **DFT in NWChem**, follow these steps:

  • 1️⃣ Perform a **DFT calculation** in NWChem.
  • 2️⃣ Extract **HOMO and LUMO** energies from the output file.
  • 3️⃣ Use this calculator to compute the energy gap (LUMO – HOMO).

Why is the HOMO-LUMO Gap Important? 🌍

  • 🔹 Determines **molecular stability**
  • 🔹 Influences **optical and electronic properties**
  • 🔹 Key factor in **semiconductor research**
  • 🔹 Essential in **quantum chemistry calculations**
