N2 - The nature and extent of molecular “ordering” in alternate-layer Langmuir-Blodgett films of 4-n-heptadecylamido- 4′-nitrostilbene/stearic acid and a functionalized diarylalkyne (JT11) have been elucidated using infrared linear dichroism. Comparison of intensity ratios of certain infrared bands in the attenuated total reflection and the reflection-absorption spectra has been used to determine the details of the molecular geometrical arrangement from the resulting directions of the selected transition moments. This information, along with spectra of hydrogen-bonded stilbene and stearic acid C=O groups, leads to a predicted “structure” which is consistent with the observation of a rather modest nonlinear optical coefficient. This should lead to an improved design strategy for the successful production of organic nonlinear optical devices.
