Abstract. The full microscopic structure of macroscopic shocks is obtained exactly in the one dimensional totally asymmetric simple exclusion process from the complete solution of the uniform stationary nonequilibrium state of a system containing two types of particles---``first'' and ``second'' class. The width of the shock as seen from a second class particle diverges as the inverse square of its strength when the latter goes to zero. In that limit the steady state exhibits long range correlations and weakly bound states of second class particles.
