Radioracemization and radiation-induced chiral amplification of chiral terpenes measured by optical rotatory dispersion (ORD) spectroscopy

摘要: Abstract For the first time radioracemization of α (+)pinene and (−)pinene, turpentine R (−)- -phellandrene has been studied by optical rotatory dispersion (ORD) spectroscopy. all these compounds, implies a shift ORD curves toward lower levels specific rotation. The degree ( ) defined calculated for compounds studied. It found that radiation dose 1 MGy is about 4.5% compound with highest purity reaches 7–8% less optically pure demonstrating impurities can affect greatly radioracemization. In contrast general effect exerted high-energy on chiral molecules, β when irradiated show an increment their This fact measured spectroscopy amplification chirality reach 1000% in near UV. phenomenon due to formation polymer, poly- -pinene, which forms solution monomer enhancing its activity. implications theories origin life such unexpected are discussed briefly.
