Abstract:DEVELOPING A PORTABLE DEVICE TO CONTROL TEMPERATURE DURING SPECTROSCOPIC MEASUREMENTS. Temperature is a natural phenomenon that may modify the structure of chemical compounds and hence their properties. We aimed to develop a simple portable system based on the Peltier principle for spectral characterization of compounds with temperaturedependent structure. The device was constructed and adapted to three pieces of equipment: X-ray diffractometer, vibrational spectrophotometer, and electronic spectrophotometer. … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
