摘要
The chromatographic behaviour of alpha- and beta- alkylnaphthyl ketones at different temperatures on the silver-loaded stationary phase is described based on the QSRR model. Complexation via an oxygen atom is favoured over the interaction through the aromatic fragment. The QSRR model and DFT/MP2 studies suggest that retention times of alkylnaphthyl ketones on silver-containing stationary phases are determined primarily by the dipole moment, length of the alkyl substituent and concentration of modifier in the mobile phase.
