As a chemist, I cannot perform ab initio calculations directly through this platform. However, I can provide you with a general understanding of how the change in molecular geometry affects the electronic properties and charge distribution of a given molecule, and guide you on how to perform ab initio calculations using computational chemistry software.The molecular geometry of a molecule plays a crucial role in determining its electronic properties and charge distribution. Changes in molecular geometry can lead to changes in bond lengths, bond angles, and dihedral angles, which in turn can affect the electron distribution, molecular orbitals, and overall molecular stability. These changes can significantly impact the molecule's reactivity, polarity, and interaction with other molecules.To perform ab initio calculations, you would need to use computational chemistry software such as Gaussian, ORCA, or GAMESS. These programs use quantum mechanical methods to calculate the electronic structure and properties of molecules. Here is a general outline of the steps you would need to follow:1. Choose a molecule: Select a molecule of interest for which you want to study the effect of changes in molecular geometry on its electronic properties and charge distribution.2. Define the molecular geometries: Create different molecular geometries by varying bond lengths, bond angles, and dihedral angles. You can start with the optimized geometry and then make systematic changes to study the effects.3. Set up the input files: For each molecular geometry, create an input file for the computational chemistry software. This file should include information about the molecule's atomic coordinates, basis set, and the level of theory e.g., Hartree-Fock, DFT, or post-Hartree-Fock methods like MP2 or CCSD .4. Run the calculations: Use the computational chemistry software to perform ab initio calculations for each input file. This will generate output files containing information about the molecule's electronic structure, molecular orbitals, and other properties.5. Analyze the results: Compare the calculated properties for each molecular geometry, such as the total energy, dipole moment, and atomic charges. Look for trends or patterns in the data that indicate how changes in molecular geometry affect the electronic properties and charge distribution.6. Interpret the findings: Based on your analysis, draw conclusions about the relationship between molecular geometry and the electronic properties of your chosen molecule. Consider how these findings might impact the molecule's reactivity, stability, and interactions with other molecules.By following these steps, you can gain valuable insights into how changes in molecular geometry affect the electronic properties and charge distribution of a given molecule. This information can be useful for understanding the molecule's behavior, designing new molecules with specific properties, or predicting the outcomes of chemical reactions.
