The infrared spectra (of CCl4 solutions) and the Raman spectra (of the neat liquids) of the eight isomeric methyl cis-undecenoates, of methyl undec-10-enoate, and of the nine isomeric methyl undecynoates have been obtained. Conjugation of the double bond with the carbonyl group lowers the wavenumber value of ν(CC) by 8 cm−1 from the mean value of 1657 cm−1. Conjugation of the triple bond with the carbonyl group gives rise to a single Raman band due to ν(CC) at 2241 cm−1 whereas the non-conjugated, non-terminal triple bond gives a Fermi resonance doublet at 2234 and 2293 cm−1.
