Hello Vladimir,
Here is the weird thing. The vibrational analysis says there is an imaginary mode (as you can see we run the frequency and pipe that into the IRC):
----------------------------------------------------------------------------
Normal Eigenvalue || Projected Infra Red Intensities
Mode [cm**-1] || [atomic units] [(debye/angs)**2] [(KM/mol)] [arbitrary]
------ ---------- || -------------- ----------------- ---------- -----------
1 -295.810 || 0.036177 0.835 35.267 20.733
2 -0.000 || 0.000044 0.001 0.043 0.025
3 -0.000 || 0.000015 0.000 0.014 0.009
4 -0.000 || 0.000013 0.000 0.012 0.007
5 0.000 || 0.000039 0.001 0.038 0.022
6 0.000 || 0.000037 0.001 0.036 0.021
7 0.000 || 0.000022 0.001 0.022 0.013
8 124.486 || 0.002547 0.059 2.483 1.460
9 146.712 || 0.000637 0.015 0.621 0.365
10 185.619 || 0.001857 0.043 1.810 1.064
11 207.290 || 0.000024 0.001 0.024 0.014
12 236.593 || 0.001386 0.032 1.351 0.795
13 273.500 || 0.003481 0.080 3.393 1.995
14 308.056 || 0.005062 0.117 4.935 2.901
As for setting it to forward direction, sometimes it gives me the same "energy increased" error, other times it works fine.
