Structural changes in pure citronellol after exposure to different doses of gamma radiation were elucidated by spectroscopic techniques and molecular modelling methods. The citronellol samples were irradiated in an MPX-g30 installation ( 60 Co, E ¼ 1.25 MeV), absorbing in a dose range from 1.45 to 10.02 kGy. Citronellal and hydroxycitronellal compounds were detected in the irradiated samples. Some mechanisms of radiolytic transformations for citronellol were proposed and modelled at semiempirical quantum chemical level. These results provide the basis for the possible development of new synthetic pathways for close structurally related compounds, based on the use of gamma irradiation.
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.
