NTChem

  • Level of openness 1 ★☆☆
  • Document quality 2 ★★☆

An application for molecular science simulation. This application covers not only traditional simulation methods implemented in existing applications but also a number of novel methods for quantum chemical calculation. It can perform ab-initio electronic state calculation for a few thousands atoms/molecules as well as trace calculation of transition states in chemical reaction for a few hundreds atoms/molecules. It can also perform high-efficient massively parallel computing on large-scale parallel computers such as the K-computer.

MOPAC

  • Level of openness 3 ★★★
  • Document quality 2 ★★☆

An open-source application for semi-empirical quantum chemical calculation based on NDDO (neglect of diatomic differential overlap) approximation. This program calculates, for a given molecule or a crystal, molecular orbits and atomic forces, as well as vibration spectra, thermal quantities (heat of formation etc.), isotopic exchange effect, force constant, and so on. It can also treat radicals and ions.
