Ground and space based observations over the last years have revealed a complex structure in the jet in 3C 273. The optically faint compact radio hot spot, the optically quiet radio lobe/halo and the low brightness level in the inner part of the jet are morphological features not yet understood in terms of our standard picture of extragalactic radio sources. Most puzzling is the fact that we have to invoke particle acceleration all over the jet and not only in the strong hot spot or compact knots. This is due to the short life time of optically radiating relativistic particles. As we know from our ground-based infrared imaging that the jet's spatially resolved synchrotron continua show a strong turnover in the infrared, it is infrared photometry which gives the most stringent constraints on the continuum shape and thus the particle acceleration mechanism{s} at work. We propose to obtain a deep infrared image {F160W} to construct the synchrotron continua at 0sec point15 resolution from our HST and new VLA images. This map will allow a detailed analysis of the synchrotron continua and especially a comparison between the knot and inter-knot regions. As the cut-off frequency is a sensitive indicator of changes in the maximum energy the radiating particles acquired, a detailed map of the turnover frequency will point to places where the efficiency of particle acceleration mechanism deviates from its mean.
