Introduction

Sparrow is a code for fast semiemprical quantum chemical calculations. It provides the following methods:

  • MNDO

  • AM1

  • RM1

  • PM3

  • PM6

  • non-SCC DFTB (DFTB0)

  • DFTB2

  • DFTB3

Sparrow can calculate electronic energies as well as nuclear gradients and Hessians.
