Fourier Transform Infrared Vibrational CircularDichroism: Improvements in Methodology and Mid-Infrared Spectral Results

We report FT-IR-VCD recorded under improved conditions of signal-to-noise ratio, resolution, and spectral range (to 800 cm −1 ). Detailed descriptions are provided in the areas of artifact suppression, phase correction procedures, and comparison of FT-IR to dispersive VCD measurements. Spectral evidence supports the proposition that VCD absorbance artifacts are a surface effect originating at the optical window-solution interface.
