You have to keep an eye out for the C-C-O asymmetric stretch, found in the fingerprint region between 1000 and 1210 cm-1. Unsaturation on an adjacent carbon lowers the frequency of the C-O absorption. Therefore, primary alcohols usually have a C-C-O asymmetric stretch band between 1000 and 1075 cm-1. grantor retained annuity trust sample
