Abstract

A correlation between the electronic structure and biological activity of chosen dichlorodiphenyltrichloroethane (DDT)‐type insecticides: 1,1,1‐trichloro‐2,2‐bis(4‐chlorophenyl)ethane, 1,1‐dichloro‐2,2‐bis(4‐chlorophenyl)ethane, 2,2‐bis(p‐chlorophenyl)‐1,1‐dichloroethylene, 2,2‐bis(4‐chlorophenyl)ethanoic acid and 4,4′‐dichlorobenzophenone (used in agriculture) has been analysed on the basis of the ^35^Cl‐nuclear quadrupole resonance (NQR) spectroscopy. The ^35^Cl‐NQR resonance frequencies measured at 77 K have been correlated with the lethal dose (LD~50~) parameter that characterises the biological activity of these insecticides.
