This article is a 'stub' about water and/or ice. It has no, or next to no, content. It is here at the moment to help form part of the structure of SklogWiki. If you add material to this article, remove the {{Stub-water}} template from this page.

The SWM4-DP model [1] [2] of water has a TIP4P like structure, as well as incorporating a Drude oscillator.
