DFT/CIS calculations were performed using either B3LYP or CAM-B3LYP, as discussed in Section II A, with B3LYP/CIS representing Grimme's original parameterization [Eq. ( )] 9 and CAM-B3LYP/CIS as the new parameterization [Eq. ( )]. Conventional TD-DFT calculations were also performed using these two functionals, as a point of comparison, along with TD-SRC1-r1 and TD-SRC1-r2 calculations. These two SRC functions are different parameterizations that are intended for use with second-row atoms (r1) or third-row atoms (r2).
