35Cl nuclear quadrupole resonance and molecular-orbital studies of DDT-type insecticides
Abstract
The 35Cl n.q.r. frequencies have been measured for the following insecticides: p, p′-DDT, p, p′-DDD, p, p′-DDE and p, p′-DDMU. Quantum-chemical calculations have allowed us to correct previous assignments of the resonance frequencies. Their insecticidal activities have been correlated with the depth of minima in the molecular electrostatic potential.
