Z. Latajka et H. Ratajczak, MOLECULAR-STRUCTURE OF BETAINE AB-INITIO STUDY, Bulletin of the Polish Academy of Sciences. Chemistry, 43(2), 1995, pp. 103-107
The molecular structure and properties of the betaine, (carboxymethyl)
trimethylammonium, (CH3)NCH2COO, was investigated using ab initio (at
the Hartree-Fock and Density Functional Theory Levels) and semiempiric
al (AM1, PM3) methods.
