IRC_DELTA0 = real
Default: IRC_DELTA0 = 0.0015 

Description: Defines the tolerance factor in Å used in the IRC calculations.


The smaller the value of IRC_DELTA0, the closer the computed IRC trajectory follows the true IRC pathway. However, a small tolerance factor necessitates more time steps and, thus, computational effort.
