orca-uv-vis

Generate ORCA input files for TD-DFT UV-Vis calculations and parse/plot the resulting absorption spectrum. Use when the user asks about UV-Vis spectra, absorption spectra, TD-DFT calculations, excited state calculations in ORCA, or wants to plot results from an ORCA TD-DFT output file. Also trigger when the user mentions oscillator strengths, electronic transitions, or simulated UV-Vis.
