摘要：
FTIR spectroscopy is used to compare the difference in molecular structure between Langmuir-Blodgett (LB) films (transferred at the surface pressure 40 mN/m with the vertical method and 0 mN/m with the horizontal method) and bulk sample of N-Octadecanoyl-L-alanine amphiphiles. The bulk sample possesses a very similar microstructure (intermolecular hydrogen-bonding interaction and triclinic chain packing) to the well-ordered LB films. Much information on molecular structure of the bulk sample is obtained using FT-Raman spectroscopy, and several weak Raman scattering peaks are assigned. (C) 2003 Elsevier B.V. All rights reserved.
