The NWChem software as been used to examine many nanoscale systems and their properties over the years. In this paper, an overiew of the general capabilities of NWChem is given as well as more specific details on the planewave and Gaussian based density functional codes usually used for nanoscale investigations. Examples are given of the scientific literature using NWChem, as well as two case studies: 1) Band gaps in oxides using exact-exchange based exchange-correlation functionals with the planewave DFT module, 2) Optical properties of chromophores using the Gaussian based DFT module.
