研究成果概要

Infrared Stark spectra for a Nylon 6 film were measured under electric fields from 0.99 to 1.5 MV/cm at 77 K using a sandwich-type cell with a BaF2/Al/Nylon 6/Al structure. The broad asymmetric infrared and Stark spectra observed for amide I (C=O stretch) were fitted with three components: 1637-cm−1 band (b-sheet structure), 1645- and 1663-cm−1 bands (disordered hydrogen-bonded structures). The change in the dipole moment between the ground and the first excited vibrational states for amide I (b-sheet structure) was determined to be 0.064 D/f, where f is a local field correction factor.
