I am trying to optimise to a minimum geometry, which means that I should get all positive frequencies for the normal modes. By default, I know that MOLPRO does a search for a minimum. But in my output, even though it has completed the optimisation in 5 steps, it still gives me one imaginary frequency in the search for a minimum. I am not sure what is wrong, since the optimisation seems to be complete, yet its unable to locate a minimum. Any input/suggestion would be helpful..<br clear="all">
