MarvinSketch : NOT List

A NOT List is a query atom that allows you to define a list of elements that should not be included in the target structure.

To add a NOT List to the molecule

1. Select the NOT List button in the Periodic Table,
2. Select the elements to be included in the list. Move the mouse into the canvas and click to add a query atom representing this NOT List.
   
   

You can create NOT Lists without opening the Periodic Table.

1. Move your mouse over an empty space of the canvas.
2. Type an exclamation mark first, then start typing the chemical symbols you wish to add to the NOT List. The entries of the NOT List must be separated by commas (e.g., !au,pt,ag). You can use Backspace to delete errors. The items of the NOT List are displayed on the upper left corner of the canvas and concurrently at the tip of the pointer (e.g., ~L![Au,Pt,Ag]).
3. Click on the query atom you want to add this NOTList.
   
   

You can move your mouse over the appropriate atom of a molecule or make selections on one or multiple atoms of the molecule before creating the NOT List as a different manner.

1. Type exclamation mark.
2. Type the chemical symbols separated by commas. The NOT List adds directly to the selected atoms.
