Gaussian frequency job after optimization

  1. Jun 16, 2010 #1
    Hi,

    I already got some good Gaussian-help in this forum, so maybe somebody can help me once again :)
    I did an optimization run for my structure in Gaussian and didn't know, that I could have combined this with a frequency calculation. So now I have to start a new frequency job based on my optimized geometry.

    My question:
    Can I somehow directly feed in the old Gaussian output or checkpoint file into the new job?
    Because at the end of the optimization run I have all the informations on the approximated wavefunction for the optimized geometry, so I think it would be very inefficient if Gaussian would have to recompute all of this for a frequency job.
    So is there any way, to re-use more than just the optimized positions of the atoms?

    Thanks in advance,
    angu
