I recently ran an optimization on a Perfluoro-2-Azopropene molecule using
MP2 (Gaussian 98) to locate the transition state. I used the opt=Z-Matrix
command in order to freeze the bond angle between the C-N=C bond. I was
able to get the transition state I was looking for using this option, but
now I would like to run the optimization again without using the Z-Matrix
command to see if I still get the transition state. I would like to use
the checkpoint file from the original job, but without the constraint. How
do I go about doing this?
