A theoretical study on the second harmonic generation properties of molecules and crystals of 4, 5-bis (2', 4'-dinitrophenylthio)-1, 3-dithiole-2-one (BNPT-DTO) and 4, 5-bis (2', 4'-dinitrophenylthio)-1, 3-dithiole-2-thione (BNPT-DTT)

On the basis of ZINDO method, the program for the calculation of nonlinear second-order optical susceptibilities βijk has been devised according to the formula of sum-over-states and the values of molecules of BNPT-DTO and BNPT-DTT have been calculated under condition of second harmonic generation. The relation of nonlinear second-order optical suseptibilities between molecules and crystals of BNPT-DTO, BNPT-DTT is analyzed at the molecular level, the computation results are in better agreement with the experimental results.
