On nonequilibrium processes in moderately dense polyatomic gas in external magnetic field

The dissipative and relaxation processes in moderately dense polyatomic gas in external magnetic field are considered by using quantum kinetic theory methods. The momentum and energy fluxes and transport coefficients are obtained in dissipative Navier–Stokes approximation taking into account the first virial correction. The tensor coefficient of shift viscosity in gas of diamagnetic molecules is obtained as a function of binary and ternary effective cross sections and a value of the magnetic field. The Bloch equation for magnetization in space homogeneous gas of linear diamagnetic molecules is derived. Relaxation times and the shift of Larmor's frequency due to intermolecular collisions are obtained.
