Worked on the VeloxChem repository to deliver advanced visualization and analysis features for computational chemistry workflows. Developed animated vibrational and spectral plotting tools, convergence and optimization trajectory visualizations, and interactive molecular displays, all using Python, matplotlib, and py3Dmol. Enhanced conformer analysis by implementing unique conformer filtering with Boltzmann weighting and refactored sampling logic for maintainability. Addressed robustness in conformer availability displays by deriving counts from actual data structures, reducing runtime errors. Added unit-flexible UV-Vis spectrum plotting and visualization of molecular charges and dipole moments, streamlining scientific interpretation and reporting for spectroscopy and molecular modeling tasks in research environments.

May 1, 2025May 2025 monthly summary: Delivered a critical robustness fix for the Conformer Availability display in VeloxChem. The fix computes the number of available conformers from the actual energies stored in the conformer dictionary rather than a hardcoded list length, preventing errors when requested conformers exceed availability. Implemented under commit 72058a7c0410ed8365b01c30dbf1209337bd95b4 (fixed show_conformer), reducing runtime errors and improving user trust in conformer queries. This work enhances reliability for molecular conformation analysis and supports downstream workflows relying on accurate conformer counts.

Jan 1, 2025January 2025 VeloxChem monthly summary: Two major feature areas were delivered with a strong emphasis on visualization fidelity and user-facing interpretability. Vibrational and spectral plotting enhancements shipped, adding animation for vibrational analysis (IR/Raman), mode details, and animated normal modes, along with refined UV/ECD and IR/Raman spectral plotting and several plotting quality improvements. Optimization visualization enhancements introduced convergence plots, animation of the optimization trajectory, and improved interactive defaults (starting step, title, geometry display controls) with better Molecule.show integration and atom index display. Several stability and correctness fixes were applied across the plotting stack, including integer x-axis enforcement and targeted plot fixes. Overall, these changes improve scientific interpretation of results, accelerate model validation, and enhance end-to-end visualization workflows for spectroscopy and optimization. Technologies demonstrated include Python-based plotting integration, LinearResponseDriver plotting functions, Molecule.show usage, and enhanced visualization utilities.
