We present molecular-orbital x-ray spectra from collision systems with highly charged projectiles calculated with a time-dependent coupled channel method using relativistic molecular Dirac-Fock-Slater wave functions and full radial and rotational couplings. The spectra of the system ${\mathrm{Cl}}^{16+}-\mathrm{Ar}$ are investigated with respect to the dynamics and the number of electrons in the system. Two basis sets have been employed in the calculation, one which belongs to the ground-state configuration and the other to the transition-state configuration on the incoming part of the trajectory respectively. Very good agreement with the experimental results is found by using the transition state basis set.
