For the first time quantum chemical MNDO method has been used for the calculation of a classical row of monoaminocarbonic acids of glycines, α-alanines, β-alanines, valines, isoleucines, norvalines and γ–aminobutyric acids, leucines and phenylalanines. The optimized geometrical and electronic structure of these compounds has been received.

The Density Functional Theory

In this work, we performed a quantum-chemical calculation of some epoxy molecules: 1,2-epoxy-butene, 1,2-epoxy-2-methylpropane, 1,2 epoxyethane by the density functional theory DFT. An optimized geometric and electronic structure of these compounds is obtained. It was found that the studied epoxides belong to the class of very weak СH-acids (pKa = 28-30).

Method Of Density Functional

In this work, we performed a quantum chemical calculation of cyclohexeneoxide and cyclopentenoxide using the method of density functional DFT. An optimized geometric and electronic structure of these compounds is obtained. It was established that the studied oxides belong to the class of very weak CH-acids (pKa = 28-30).
