Kemizoo is a free 3D molecule manipulation tool. The software is suitable for chemistry education as well as entertainment, everybody can link or embed the molecules to their homepage. Currently, database contains ~350 structures. Web pages :
Kemizoo - the structure fills the window, it is possible to select molecules in topics given.
Kemizoo quiz - guess up to 100 molecules by rotating 3D structures. There are 10 levels in the game (random, inorganics, IUPAC, polymers, funny names, biochemistry, amino acids, food, poisons, explosives). You must get at least 10 points to get to the next level. Every correct answer gives 2 points, but wrong one -1p and seeing Hint2 also results -1p.
You can move a molecule by various ways: using mouse or arrow keys, key "a" moves z-axis, and the structure rotates faster if you hold down shift key.
Double click on an atom selects it - it becomes yellow and the symbol will be visible. Distance between two atoms can be seen in the left down corner if two atoms are selected (but the buttons must be visible, mouse meny->buttons). By selecting four atoms, it is possible to get a plane by clicking button … .
Zoom in or out: a) mouse scroll button b) +- button in the meny c) mouse meny->zoom 20% d) key p (zoom in) or m (zoom out).
Show element symbols: Tab key or mouse meny->symbol.
Representation: ball-and-stick, sticks, wireframe, spacefilled. Style can be changed from a) buttons …, b) mouse meny>style, c) by pressing key space (but first click at the molecule to select it).
Automatic rotation a) button …, b) mouse meny -> rotate, c) keys x,y,z.
Full screen option can be initiated from button … or by pressing key f. NB! Only the following keys work in full-screen mode: space, arrows, shift, tab.
Background color: black, white, transparent (or brown) - button … or mouse meny-> background color.
It is possible to use green carbon atoms (instead of usual grey) by pressing button … .
Molecules can be selected from dropdown meny "Select topic". If the window is too small to open the list, go to full screen (click and key f) and try again.
To obtain the address of the structure, choose desired properties (such as representation style and angle of the molecule) and select from mouse meny->get URL. Sample code to embed a molecule to your web page:
<iframe src="http://chemicum.com/zoo/embed.html?file=crystal_structure/NaCl.xml&style=ball_and_stick&angles=-27,-15,-92&bg=FFFFFF&meny=false" width="240" height="160" marginwidth="0" marginheight="0" frameborder="0"></iframe>
the following three molecules have been obtained by some changes in the embed code:
