What Does ORSTB Stand For?

ORSTB stands for Overlap Reduced Semiempirical Tight Binding

ORSTB, or Overlap Reduced Semiempirical Tight Binding, is a computational method used in quantum chemistry and condensed matter physics to simplify the modeling of molecular and solid-state systems. By reducing overlap between atomic orbitals, ORSTB enhances computational efficiency while maintaining accuracy in predicting electronic properties and interactions. This approach is particularly valuable for large scale simulations where traditional methods become computationally prohibitive, allowing researchers to explore complex systems with greater speed and flexibility.
