I have been having some trouble analyzing this IR spectra and labeling all the peaks such as C-H stretch etc. not sure if this is allowed but here are 2 links, one of my IR spectra and the other of characteristic IR absorptions. Im assuming the peak just below 3000 cm-1 is a C-H stretch, the peak at about 1600 C=C, the next largest peak being C-H bend then C-H "oop", and finally just to the right C-H rock. any help is much appreciated and i will rate high.
