Elastic, ionization and total cross section for electron scattering from pyrrole and its isomers, viz. 2H-pyrrole, 3H-pyrrole, cycloprapanecarbonitrile, E-2 butenenitrile and Z-2 butenenitrile are reported in this article. These cross sections are calculated using the spherical complex optical potential formalism and the complex scattering potential-ionization contribution method in the energy range from the ionization threshold of the molecule to 5 keV. The geometric screening correction is used to reduce the overestimation of cross section due to overlap in charge distribution among atoms or group of atoms in the molecule. The isomeric effect through cross section values are also investigated in this work. The cross section data reported in this paper are key input for modeling Titan’s atmosphere due to the presence of pyrroles and abundant electrons in its medium.
