WebThe minimum-energy structure for 6was only obtained using the “opt=verytight”, “int=(grid=ultrafine)”, “cphf=(grid=fine)” and “scf=tight” keywords in Gaussian09. The amount of spin-contamination in the open-shell calculations is less than 6 % in all cases. Web- check if the geometry is reasonable - integral (grid=ultrafine) is basically mandatory for any DFT, use it - do the optimization first in the 6-311g (d) basis set (the + diffuse functions may sometimes cause convergence problems). If it finishes OK, use the final geometry and reoptimize with +. sharon brawner nashville https://smidivision.com
