For the 9-anthraldheyde spectrum, the peaks at just over 3000 cm-1 indicates the presence of sp2 carbon hydrogen bonds. The peaks at 2858.3 and 2772.1 cm-1 shows the presence of an aldehyde. The peak at 1664.0 cm-1 indicates the presence of a carbon oxygen double bond, more specifically conjugated with a phenyl group. The two peaks at ~1600 and ~1550 cm-1 along with the overtones located around 1900 cm-1 indicates the presence of a benzene ring. For the product, the peaks located just over 3000 cm-1 indicate carbon hydrogen bonds. The weak carbon-carbon double bond peak located at 1621 cm-1 indicates the presence of a trans alkene. This is also supported by the peak located at 964.93 cm-1, the trans isomer peak. The two peaks at 1621.31 and 1516.29 cm-1 along with the overtones located around 1900 cm-1 indicates the presence of a benzene ring. Based on this data, it can be concluded that a successful Wittig Reaction occurred to produce the trans
