摘要

本研究构建了一种具有热电冷却探测器（TEC单元）的振动圆二色性（VCD）仪器。在仪器中使用电子装置代替液氮来冷却探测器。通过记录液体蒎烯和昆虫翅膀的VCD光谱，验证了该系统的可行性。VCD信号是在恒定的基线下获得的，稳定时间超过40小时。配备TEC单元的光谱仪显示出进行长时间测量的潜力。

Construction of a Vibrational Circular Dichroism Instrument Equipped With a Thermoelectrically Cooled Detector for Prolonged Measurements

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.

期刊介绍： The main aim of the journal is to publish original contributions of scientific work on the role of chirality in chemistry and biochemistry in respect to biological, chemical, materials, pharmacological, spectroscopic and physical properties. Papers on the chemistry (physiochemical, preparative synthetic, and analytical), physics, pharmacology, clinical pharmacology, toxicology, and other biological aspects of chiral molecules will be published.
