Astronomers are still far from understanding in any detail what an HH object really is. There is more or less general agreement that the emission line formation takes place in recombination regions of shock waves (Schwartz 1975, Böhm, Siegmund and Schwartz 1976) but it is much less clear what the actual geometrical structure of the shocks is and in which way they are imbedded in the jets. The authors consider that it is useful to try to obtain more empirical information about the kinematics and the physical structure of HH objects and their immediate environment using long slit spectra of high spatial and spectral resolution. Using the vertical coude spectrograph of the 2.2-m telescope at the Calar Alto Observatory the authors have obtained spatially resolved spectra of a number of HH objects including HH 1, HH 2, HH 7, HH 8, HH 10, HH 11, HH 24, HH 28, HH 29, HH 30, HH 32, HH 39, HH 43, and HH 103.
