*   Resonance Page
The application generates fragmentation and rearrangement mechanisms along with electron shift reactions (resonance reactions). Because these reactions can cause a large number of by-products even for relatively small structures, by default, the resonance reactions are not depicted.
To keep the reaction network simple, the application reduces reaction complexity by not displaying resonance reactions. As a result, elementary reaction steps that include resonance reactions are merged into a single step. If you have difficulty understanding such reduced mechanisms, you can display all resonance reactions.

Display This Window Every Time Generation of Fragments & Mechanisms Is Started
Opens the Reaction Restrictions dialog box each time you start fragment generation. Clear this check box if you want to use the same parameter settings for subsequent fragment generations and do not want to see this dialog box each time.
If you clear this option and want to return to displaying the Reaction Restrictions dialog box each time you start fragment generation, follow the instructions To restore the Reaction Restrictions dialog box each time you start fragment generation.
Restores all default values in the Reaction Restrictions dialog box. These values take effect after the regeneration of fragments and mechanisms and affect all subsequent generations. The current Fragments & Mechanisms windows are not affected.
