文摘The research of the complex compounds between the crown ethers and metal ions has become more extensive since the first study of Pedrsen in 1967. The catalysis and separation property of crown ethers are important. It is necessary to study the nature of these compounds. The present note reports the MCD spectra of 4-substituted benzo-15-crown-5.
