The model provides a comprehensive description of fission dynamics by simultaneously accounting for collective vibrational modes (bending and wriggling) and their influence on spin distributions while systematically investigating the deformation dependence of moments of inertia. Our calculations demonstrate close agreement with experimental data, validating the model's reliability for both fundamental nuclear fission studies and practical applications in reactor physics. The unified treatment of macroscopic and microscopic effects offers new insights into fission mechanisms and enables accurate predictions of fragment characteristics across the entire mass range. These results provide a solid basis for future studies on exotic fission processes and advanced applications in nuclear energy. The methodological advances presented here create new possibilities for theoretical studies of various heavy-ion reactions and fission phenomena in superheavy nuclei."> Evaluation of the moments of inertia of forced split fragments for <sup>232</sup>Th (<i>n</i>, <i>f</i>) and <sup>238</sup>U (<i>n</i>, <i>f</i>) nuclei -
