I have perform Opt+Freq calculation with Gaussian 03 and the frequency symmetry obtained is ?A. what does this mean and how do I formally represent this frequency symmetry.
Any help will be greatly appreciated

Which DFT potential and basis set you will recommend for squarine molecule which possesses four 90 valence bond angles in the center (i.e. possesses high strains)? With best regards, Arvydas Tamulis
