Context: The structural, electronic, and nonlinear optical properties of Verdoocridone A (Ver A) and B (Ver B) are examined theoretically in this study. The results showed that Ver A and B exhibit good electronic properties and can be used as new materials in NLO applications. According to their maximum absorption wavelength, Ver A (λ max  = 313 nm) enables production of vitamin D, while Ver B (λ max  = 319.55 nm) can help skin pigmentation., Methods: All calculations were performed at the DFT/B3LYP-D3/6-311 + G(d,p) level of theory using the Gaussian 16 software package. Excited states were simulated using the TD-DFT method at the CAM-B3LYP combined with 6-311 + (d,p) basis set. Also, the solvent effect was studied in water and benzene phases by the solvation model based on density (SMD) method., (© 2024.
