Abstract

IR lines are calculated for AGN by SVMA code. IR line ratios, as temperature and density diagnostic of the emitting gas, show that the [S III] lines ratio increases with shock velocity, following compression and cooling of the gas downstream. The results are compared with observations and briefly discussed.
