Supplementary material for "Probing the photoabsorption features and electronic levels of propylene oxide: an experimental and theoretical study"

Photoabsorption cross section for propylene oxide in the 6.0–10.8 eV range are included as obtained experimentally and by theoretical approximation. Experimental spectrum Vertical approximation based in the TDDFT/CAMB3LYP/aug-cc-pVQZ calculation Ground state frequencies (in cm‐1) of propylene oxide and propylene oxide cation Calculated vertical excitation energies (in eV) and oscillator strengths (f0) obtained at TDDFT/CAMB3LYP/aug-cc-pVQZ, TDDFT/CAMB3LYP/aug-cc-pVTZ, TDDFT/B3LYP/aug-cc-pVTZ levels of theory.
