You need to <br>
find the transition state.<br>
<br>
In the mixer there is a nice option, namely to use a constraint.<br>
With this option you can eg. drive an atom from (X1,y1,z1) to a final <br>
position, with the constraint that eg. the z1 coordinate should increase <br>
to a certain value z2 (corresponding to the final state). x2,y2 will <br>
follow the forces and get optimized (provided the movement along z is <br>
not too fast.<br>
<br>
It works quite well, once you have found the proper parameters driving <br>
the movement via some pseudoforces.<br>
<br>
Please checkout in SRC_mixer the corresponding doku.<br>
