Jayantilal. G. Raiyani

One of the most exciting aspects of the astrophysics is the continued discovery of the wide range of molecular species. The polyatomic molecules like as CH3OH, CH3CHO and CH3CN detected in interstellar space matter have been covered in present study. In this paper, we report a theoretical study on electron scattering by polyatomic molecules in the low-energy range. The rotational excitation total cross sections (TCS) are calculated for electron scattering by polyatomic interstellar space molecules like as CH3OH, CH3CHO and CH3CN at the energy from 0.5eV. to 16.5eV. The Born Eikonal Series (BES) Approximation method is employed for present calculation and using the hard sphere dipole interaction potential model for electron-molecule interaction. The results obtained for present calculation are compared with experiment and theoretical data available in the literature
