Notes:
The Raman spectra of α-octyl-ω-methoxyoligo(oxyethylene)s, CH3(CH2)7(OCH2CH2)mOCH3 (m = 1-4), were measured in the solid state. The molecular conformation of these compounds was determined by a spectral analysis based on the key conformational bands. The conformation of the inner oxyethylene segments changes from an extended structure to a helical structure as the number of oxyethylene units increases. The difference in the conformational behaviour between the present methoxy-ended compounds and the corresponding hydroxy-ended compounds is associated with the different layer structures of the crystals.
