Abstract

Special chemical impurities may greatly decrease the light transparency of liquid scintillator LS solvents in the wavelength region 350–450 nm which is of great importance to the neutrino experiments The absorption wavelengths and oscillator strengths of two types of impurities thiocarbonyls and nitrobenzene derivatives and some similar compounds were calculated using TDDFT in three scintillator solvents toluene pseudocumene and linear alkyl benzene Influences of these impurity molecules on LS solvent’s optical transmission in 350–450 nm were analyzed and compared with each otherThe authors are thankful for the helpful discussions and suggestions from Chen ShenJian Ma Jing Li ShuHua Zou ZhiGang and Li ZhaoSheng This work was supported in part by the National 973 Project Foundation of the Ministry of Science and Technology of China Contract No 2006CB808100 the project of Shanghai Synchrotron Radiation Facility SSRF and the project of laboratory of Nuclear Detector and Electronics Institute of High Energy Physics Chinese Academy of Sciences
