NMR spectroscopic investigation of hydrogen bonding in atrazine
Article Abstract:
Nuclear magnetic resonance was used to study atrazine's solution properties. The results indicated that atrazine in aprotic solvents is present in the form of a combination of four conformational isomers. The isomers' restricted rotation around the alkylamino side chains is the result of the partial double-bond character, which indicates that a separation of charge exists in the molecule. This separation allows atrazine to donate and accept hydrogen bonds.

Cooperative hydrogen bonding of atrazine
Article Abstract:
The determination of formation constants for the complexation of atrazine with soil organic matter functional groups is discussed. Formation constants of pyrrolidinone and acetic acid were calculated by titration and linear regression procedures. Nuclear magnetic resonance spectroscopy was used to observe chemical shifts. The utility of atrazine hydrogen-bonding parameters for predicting complexation in an organic solvent was demonstrated.

Atrazine hydrogen-bonding potentials
Article Abstract:
The measurement of formation constants for hydrogen-bond complexation with donors and acceptors of hydrogen bond for the evaluation of the hydrogen- bonding potential of atrazine is discussed. Nuclear magnetic resonance spectroscopy was used to observe eight hydrogen-bonded atrazine complexes and linear regression calculated their formation constants. The utility of atrazine potential for estimating formation constants was demonstrated.
