Structural, electronic, and NLO properties of two acridone alkaloîds: DFT and TD-DFT studies.

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 = 313 nm) enables production of vitamin D, while Ver B (λ = 319.
