How do I include these….or do I even need to. Also need one or two more literature sources – must be from chemistry journals The IR spectrum presented a broad peak in the range of XXX – XXX cm-1 range. The typical absorption frequency for ketones around 1700 cm[1 is not present either, which is a sign of transformation of starting materials. The inconclusiveness of the IR spectrum is caused by a very low sample concentration. The GC spectrum shows interesting retention time differences at 4.021 and 4.134 minutes, which can be assigned to the presence of axial and equatorial alcohol stereoisomers, respectively. This is due to cis-isomers having a higher boiling point due to hydrogen bond aggregation and slower elution through the GC column.
