Reflection–absorption FT-IR spectroscopy of pentadecanoic acid at the air/water interface
Sinnamon, Brendan, Dluhy, R.A., & Barnes, G.T. (1999) Reflection–absorption FT-IR spectroscopy of pentadecanoic acid at the air/water interface. Colloids and Surfaces A: Physicochemical and Engineering Aspects, 146(1), pp. 49-61.
Reflection–absorption Fourier transform infrared (RA FT-IR) spectra of spread monolayers of pentadecanoic acid have been obtained for a range of surface pressures at 292 and 297 K. Unpolarised and s- and p-polarised radiation at 30° angle of incidence have been used. Results in the C–H stretching region reveal disorder in the arrangement of the acyl chains with numerous gauche bonds when the monolayer is in the liquid expanded (LE) phase and highly ordered chains with mostly trans bonds in the condensed phases (LC and S). The transition from one form to the other occurs at nearly constant surface pressure in the LE↔LC coexistence region.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
