Abstract

A new FT-IR vibrational circular dichroism (VCD) spectrometer has been assembled to record VCD spectra with excellent signal quality up to ~650 cm⁻¹. A special detector with 600 cm⁻¹ cutoff (<i>D</i>* = 4 × 10¹⁰), a ZnSe modulator, and a KRS-5 polarizer were used in these measurements. Typical VCD spectra at 4 cm⁻¹ resolution, can be obtained within a one-hour data acquisition period, while those at 1 cm⁻¹ resolution, in the ~1500-650 cm⁻¹ region, can be obtained within four hours of data acquisition per sample. VCD spectra for α-pinene, 3-bromocamphor, and propylene oxide are presented.
