What Does GTG Stand For?
GTG stands for Gaussian Type Geminal
GTG, or Gaussian Type Geminal, refers to a mathematical function used in quantum chemistry to describe electron pair interactions in molecular systems. It is characterized by its Gaussian-shaped spatial distribution, which simplifies the computational modeling of molecular wave functions and enhances the accuracy of electronic structure calculations. GTG functions are often employed in various quantum mechanical methods, including Hartree-Fock and post-Hartree-Fock theories, to improve the representation of electron correlation effects in multi-electron systems.
