If you have a browser plug-in or other program which can read pdb (protein database format) file such as the Chime plug-in or the Chem3D Net plug-in then you can view the element structure interactively. For help in viewing the interactive images linked to from this this page, try this link. If you have a virtual reality (VR) plug-in such as Cortona (make sure you get the VRML1 converter as well) or CosmoPlayer [Mac VRML applications and other VRML applications] then you can view interactive 3D images. The "large image" link will give you a full window display of the interactive file and you will have to use your browser "back" button to get back to this page. The "small image" link will give you a smaller display of the file embedded within this page. The images were constructed using the CrystalMaker program. , , , , . |
