Electric-field -induced reorientation of a ferroeletric liquid crystal molecule without a carboxylate group near the stereocenter studied by time resolved infrared spectroscopy combined with normalized sample-sample two- dimensional correlation spectroscopy

Article Abstract:

The electric-field-induced switching of FCL-2 without carboxylate group near the stereocenter is explored by using polarised time-resolved IR spectroscopy combined with normalized sample-sample 2D correlation spectroscopy. Results show that the reorientation track of the core in the positive half-period is different from that in the negative half-period, while the reorientation track of the C=O dipole moment and the alkyl chains are very much alike between the positive and negative half-periods.

Thermal property of an octadecyldimethylamine oxide multilayer Langmuir-Blodgett film studied by an expanded model for quantitative molecular orientation analysis with infrared reflection-absorption spectrometry

Article Abstract:

Results indicate that analysis of the thermal property of octadecyldimethylamine oxide (C(sub)18DAO) multilayer Langmuir-blodgett film exhibits great disorder in the first layer of the film between 50 and 60 C. This differential thermal property between first and the rest of the layers suggests that the headgroup of C(sub)18DAO possesses strong dipole activity.

In situ examination of the structure of model reversed-phase chromatographic interfaces by sum-frequency generation

Article Abstract:

Sum-frequency generation (SFG) spectroscopy was used to examine model reversed-phase chromatographic interfacial systems. Solvent microheterogeneity had a huge effect on alkyl chain order.
