WitrynaHow to Remove Imaginary Frequency. In geometry optimization of the search of the transition state (TS), a guessed TS must has only one imaginary frequency along the normal mode of vibration. One imaginary frequency indicates that your guessed TS structure is at a saddle point, which is a potential energy maximum rather than a PES … WitrynaThe even- and odd-numbered ring transition states have different symmetry point groups. Cs transition states (even rings) have an imaginary frequency mode that transforms as the asymmetric irreducible representation of the group. C2 transition states (odd rings) have a corresponding mode that transforms as the totally symmetric representation. WitrynaThe Game of Life is an imaginary robot game (cellular automaton) ...
