As an AI language model, I cannot perform TDDFT calculations directly. However, I can guide you on how to perform these calculations using appropriate software and interpret the results.To calculate the excitation energy and wavelength of the highest energy absorption transition for benzene using TDDFT, you will need to use quantum chemistry software such as Gaussian, ORCA, or NWChem. Here's a general outline of the steps you would need to follow:1. Obtain the molecular structure of benzene C6H6 . You can either draw the structure using a molecular editor or find the structure in a database like PubChem.2. Prepare the input file for the quantum chemistry software. This file should contain the molecular structure, the method TDDFT , the basis set, and any other necessary parameters. For example, if you were using Gaussian, your input file might look like this:``#P B3LYP/6-31G d TD NStates=1 Benzene Excitation Energy Calculation0 1C 0.00000 1.40272 0.00000C 1.21479 0.70136 0.00000C 1.21479 -0.70136 0.00000C 0.00000 -1.40272 0.00000C -1.21479 -0.70136 0.00000C -1.21479 0.70136 0.00000H 0.00000 2.49029 0.00000H 2.15666 1.24515 0.00000H 2.15666 -1.24515 0.00000H 0.00000 -2.49029 0.00000H -2.15666 -1.24515 0.00000H -2.15666 1.24515 0.00000``3. Run the calculation using the software. This will generate an output file containing the results of the TDDFT calculation.4. Analyze the output file to find the excitation energy and wavelength of the highest energy absorption transition. Look for a section in the output file that lists the excited states, their energies, and wavelengths. The highest energy absorption transition will have the lowest wavelength.Remember that the specific details of the input file and the output file will depend on the software you are using. Make sure to consult the documentation for the software to ensure you are using the correct syntax and parameters.Once you have the excitation energy and wavelength, you can use these values to analyze the electronic transitions and properties of benzene.
