The cursor will change shape to indicate this. To select three atoms from the molecular display to define its connectivity. The Z-matrix window will look as follows:Ĭlick the button of the atom type you want to add. When you Click the Add Line button, you are going to add a The Apply Changes to the current Z-Mat button or hit the Return Will undo all changes to the Z-Matrix since the last time you clicked When you click the Cancel Non-Applied Changes button, you This can also be accomplished by hitting the Return key when in an The current Z-matrix will be converted toĬartesian coordinates and the changes will take affect in the molecular display. Or hit the Return key in an active variable textfield, When you click the Apply Changes to the current Z-Mat button This will reset the status of all variable to the state: variable. The status of variables: Variable, Constant, Linked Linked field, the field to which it is linked to becomes active. When you Click with the Left Mouse Button in a You want to link to, possibly indicated by a previously set mark. You will be asked to click in the variable field of the variable Link/-Link: When two variables are linked this means there.Instrumental when linking two variables which are are not Mark/Unmark: This variable is visually marked/unmarked.

Variable: This variable is to be optimised ( Default).

Constant: This variable is not to be optimised by.

You can change is status by clicking in it with the When a variable field is active, indicated by a thick rectangle drawn around it, Line will become visible in the Variables/Connectivity editing windowĪnd its atom label field will turn to color red. When you click on a atom in the molecular display, its corresponding Z-Matrix For exampleĪn Dihedral angle is made up by four atoms. On the molecule display will change color accordingly. Their color from their default greyish/brown.

The atom label field of the atoms that make up this variable will change.

To be converted to cartesians and the changes to take affect in the Such as xterm can be copied to this field by clicking in itĪpply Changes to current Z-mat button will cause the Z-matrix

(Also any text selection you have made from other active programs a thick rectangle is drawn around it to signal that it is active Īny typing you do now will effect this variable.Of a variable and to high-light the atoms which are involved in this In the variables editing window color is used to indicated the Status Third atom is connected to the first two by just a bond distance and Of course the first atom in the Z-matrix has no previously definedĪtoms to refer to and is the origin if you like, the second atom isĪlways connected to the first atom by just a bond distance variable, and the The two planes constituted by atoms (Carbon-5-4) and (5-4-3) make an.Vector from atom number 5 to atom number 4 make a The vector from the Carbon atom to atom number 5 and the.

Additional helper applications may be used to optimise The Z-Matrix Editor in molden lets the user create and/or manipulate
