Positive and Negative Chemical Ionization Mass Spectra of Polychlorinated Pesticides1 The simplicity and sensitivity of the CI spectra of drugs have resulted in the successful use of chemical ionization in the screening of crude extracts of biological fluids for drugs and poisons. 3 The extension of these methods to pesticide residue analysis is obvious but not necessarily direct.

C NMR Studies of some BicycloOctanones., Characterization of the Isomeric 1,5,5,8-Tetramethyce is presented to show that closely neighboring ´ carbons experience deshielding effects, in sharp contrast to the influence of steric crowding on y carbons. The .C shieldings observed for 1,5,8,8-tetramethylbicyclooct-5-en-2-one and the isomeric saturated bicyclooctanones obtained therefrom establish their structures.

Nuclear Magnetic Resonance Studies of the Behavior of DDT in Model Membranes behavior. Both compounds are distributed widely in the environment, tend to be concentrated in food chains and there is evidence that certain wildlife populations may be affected as a consequence. Despite the continued interest in these compounds over a number of years, the molecular basis of their toxic action is not understood.
