We assess the effectiveness of singly differential cross sections (SDCS) for electron impact ionization of water and pyrimidine molecules by applying the generalized binary-encounter-Bethe (GBEB) model. When compared to the original binary-encounter-Bethe (BEB) model, the GBEB model is developed based on corrected acceleration energies [Y.-C. Wang et al., Phys. Rev. A 109, 022804 (2024)]. The SDCS calculated by the GBEB model shows improved agreement with the experimental data compared to the BEB predictions. The agreement becomes better as the energy of the ejected electron increases. For low incident energies, the acceleration correction of the GBEB model improves the SDCS at low incident energies.
