Then select option 7, the program will ask for the file and then you select the state you want.The program will plot the difference density between the ground state and the excited state in question.Depending on the grid interval you chose, the calculation may take a few minutes.orca_plot will just interpret the NTO file as a regular GBW file that contains MOs. Don't change the jobtype, just change the orbital numbers (see NTO section of output to see which ones makes sense to plot) and then plot orbitals corresponding to NTO orbital numbers in the outputfile.
TDA calculations are usually recommended as they are cheaper and the results are very similar between the two approaches.
Full-TDDFT calculations give more accurate intensities, however.

Granted, both these points go hand-in-hand, however increasing your profits begins with...“It’s par for the course that he’ll build orcas,” she said.
Cambrin has been volunteering at the Vancouver Aquarium for eight years.
Cambrin, 27, had toyed with the idea of making a pod of five or six orcas at Jericho Beach, near his home.
Be aware of possible numerical errors due to the COSX grid, which are almost always minor (calculations on anions and with diffuse basis sets may have some grid sensitivity).
Timing and accuracy comparison of RIJONX/RIJCOSX approximations vs. This is an unrestricted B3LYP 50-root TDDFT calculation on a 347-electron system (Mo Fe3S4 cluster) with 1067 basis functions, using 6 cores: The excitation into State 1 can be well described as an orbital excitation from orbital 4a to orbital 5a.
orca_plot requires the original file and the file from the TDDFT calculation: The orca_plot program will show you a menu with options to plot different types of orbitals, densities etc.
Start by selecting the Output file format (Cube format for example), then the grid interval (determines the resolution of the plot, a value of 80 is often OK).
A relaxed excited density can also be obtained (which can be visualized using orca_plot) if the Keepdens keyword is included.
