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.
