Spiral Density Waves (SDWs) are believed to trigger star formation in spiral arms in galactic disks. We have embarked on a (optical to radio) multi-wavelength project to study the effect of a SDW in a well-selected region in M51. We see evidence that a significant fraction of on-going star formation is missed by our current tracers. Thus we request IRS high resolution spectroscopy (SH and LH) to quantify via MIR (H2,fine-structure) lines the properties of deeply embedded young star forming regions and of the warm molecular gas. This unique study will significantly increase our understanding of the physical processes that transform molecular gas into stars by taking advantage of the spatially resolved time evolution: from young molecular clouds (traced by molecular line emission) via star forming regions (seen in the IRS lines and the radio continuum) to mature stellar clusters (seen via H recombination lines, HST colors).
