<br>tightening convergence criteria you should observe a commensurate
<br>conformational change, thus, I do not aspect huge changes otherwise, the
<br>system is not really converged.
<br>Anyway, it is system dependent. To fully characterize the TS (or more
<br>TSs for multiple path reaction) you should perform other TS searches,
<br>for example, starting from different conformation of the system. You can
<br>refine the characterized TS re-doing the TS search starting from the
<br>last TS geometry obtained, but using a new randomized dimer directions
<br>set.
<br>
<br>good luck,
<br>

<br>> Hello Lucas,
<br>>
<br>> Thank you for your input. I have already ran a vibration frequency
<br>> calculation using the coordinates obtained from the Dimer Method TS
<br>> calculation. I was able to locate a single imaginary frequency using
<br>> the attached input. My MAX FORCE was 0.0004 in that calculation.
<br>> So although I was able to locate a single imaginary mode, if I were to
<br>> tighten the criteria for the TS calculation, I could see completely
<br>> different results in the vibrational analysis?

<br>> Thanks,
