摘要: Excitation energies and oscillator strengths of the first two electronically excited states helium, water, sulfur dioxide, molecular nitrogen, carbon monoxide were obtained from an asymmetric-Lanczos-based formulation equation-of-motion coupled cluster singles doubles approach. The total photoionization cross sections generated by different methodologies: analytic continuation procedure based on Pade approximants Stieltjes imaging technique. results are compared with theoretical algebraic diagrammatic construction [ADC(2)] ADC(2)-x calculations [M. Ruberti et al., J. Chem. Phys. 140, 184107 (2014)] available experimental data.Excitation data.
