Abstract:
A vibrational circular dichroism (VCD) instrument having a thermoelectrically cooled detector (denoted as a TEC unit) was constructed in this study. An electronic device, instead of liquid nitrogen, was employed in the instrument to cool the detector. The feasibility of the system was examined by recording the VCD spectra of liquid pinenes and insect wings. VCD signals were obtained at a constant baseline that was stable for more than 40 h. The spectrometer equipped with a TEC unit exhibited potential for performing measurements for prolonged time periods.
