We present the derivation of kinetic formulas modeling the microscopic interaction of a charged particle withing a molecular gas under effect of thermal motion. Both elastic and inelastic processes are taken in account. The results were verified to reproduce the non-thermal formulas when the target molecule velocity is set to zero. A set of simulation is provided to highlight the effects in Argon and Carbon tetrafluoride. Our results can applied in Monte-Carlo simulation of particle drift at energies of the same order of the thermal kinetic energy of the buffer gas.
