Dear all.<br>I am trying to use CI to search transition state.<br>The initial and final state 's structure are very different and there is no intermediate between them.<br>The transition state is easily got by Gaussian program with very small imaginary frequency.<br>
I tried two ways.<br>1 Use initial and final state and large/small num_of_images <br>2 use initial and final state, and an intermediate ( from Gaussian ts searching result)<br> Both of the ways can not successfully find the TS, The TS searching calculation does not converge.<br>
Does there anyone have experience to solve this kind of problems?<br>Thank you very much.<br>Yours,<br>Gao Min<br>
