Abstract : From the electromagnetic equations for fields, produced by point particles (electrons and nuclei) the field equations, taking into account the existence of stable atoms (or molecules, or ions) are derived in covariant form. These 'atomic field equations' involve, besides the field tensor (e,b) an atomic polarization tensor (p,m), or alternatively the field tensor (d, h) = (e + p, b  m). The atomic polarization tensor is given (up to second order in the internal atomic variables) as a function of atomic positions and velocities; proper electric dipole, quadrupole and magnetic dipole moments; and time derivatives of these quantities. (The 'proper atomic multipole moments' are defined in Lorentz frames in which the atoms are momentarily at rest). (Author)
