I am running a DFT calculation using Gaussian 05,,, but the output / log file shows the above mentioned statement. I tried with all possible changes which can be made in input file and checked the space b/w the lines and keywords, but unable to get the converged structure. Can any one help me to solve this convergence problem?
My Input file is like this..
%mem=2GB
# opt freq b3lyp/6-31g geom=connectivity
