Hydrogen Bonding Character Between the Glycine and BF4-

The hydrogen bonding character between the BF4- and glycine was theoretically studied at the level of B3LYP/6;31+G*, single point energies were performed at the level of B3LYP/6311++G**. The relevant geometrical characteristics, energy properties, as well as the characters of the intramolecular hydrogen bonds have been studied. Atoms in molecule theory topological analysis indicated the (3,1) critical points for hydrogen bonds. In addition, the electron density and Laplacian were in the range suggested for the hydrogen bonds. Especially, the changes of atomic charge, dipole moment, enegry as well as volume of the hydrogen upon hydrogen bonds formation were systemitically discussed.
