 The impacts of radiative heat-loss function and thermal conductivity have been taken into account while analyzing the effects of rotation, Finite Ion Larmor radius (FLR) corrections, and porosity on the thermal criteria of instability of infinite uniform plasma. By using appropriate linearized perturbation equations for the issue, the normal mode analysis approach may be used to get the universal dispersion relation. For the propagation of transverse waves, this dispersion equation is further condensed for rotation axes both parallel and perpendicular to the magnetic field. The stability of the medium was established via the thermal instability criteria. The effects of various factors on the pace of the thermal instability's growth have been demonstrated by numerical calculations. We infer that the growth rate of the system in the transverse mode of propagation is stabilized by rotation, FLR adjustments, and medium porosity. Our findings demonstrate how the rotation, porosity, and FLR corrections influence the organization of dense molecular clouds and star formation in the interstellar medium.
