摘要：

The solution properties of atrazine are investigated using NMR spectroscopy. In aprotic solvents, atrazine exists as a mixture of four conformational isomers related by rotation of the alkylamino side chains. The partial double-bond character responsible for this restricted rotation implies that there is a separation of charge within the atrazine molecule. As a result of this separation of charge, atrazine is able to both donate and accept hydrogen bonds. One consequence of this cooperative H-bonding is that atrazine dimerizes in aprotic solvents. In CCl4 solvent, the dimerization constant is 49 M-1.
