Measurement of Vibrational Circular Dichroism Using a Polarizing Michelson Interferometer

Fourier transform infrared (FT-IR) vibrational circular dichroism (VCD) has been observed for the first time with the use of a polarizing Michelson interferometer (PMI). VCD spectra have been recorded for (–)- α-pinene between 900 and 1350 cm −1 at 4 cm −1 resolution with excellent signal-to-noise ratio. The FT-VCD spectra are virtually the same as those recorded for (–)- α-pinene under the same conditions with the use of the more conventional double modulation FT-IR approach.
