Using the FTIR spectrum for a compound containing C, H, N and match the peaks to the appropriate type of vibration that the peak is due to. All peak labels on the spectrul are given in units of cm 1. The vibration type is only used once when matching vibration only matches to one particular wavenumber). 50 sosd 1500 2850 895 3460 2980 680 1630- 3380 1440 1295 750 1600 1470 1720 1360 1265 1000 1200 2000 POCO 1500 VENDER Alth Unaturated stretch 3 Costretch catroxylic acid 4 CO stretch for carboxylic acid Pa 5.
