英文摘要: The air/pure liquid interfaces of five kinds of short chain fatty acids of acetic acid, propionic acid, butyric acid, pentanoic acid and hexanoic acid were addressed by sum frequency generation vibrational spectroscopy(SFG-VS) under three polarization combinations(ssp, ppp, sps). The vibrational modes of spectra peaks were assigned according to the polarization selection rules. Furthermore, the orientation of the fatty acid molecules at air/liquid interface was calculated. It was found that the orientation angles increase slightly with the increase of the length of carbon chain and the possible mechanism was proposed.
