The frontier molecular orbitals (FMOs) are very important for describing chemical reactivity and understanding the static molecular reactivity. The HOMO and LUMO energies of 1,3,4-thiadiazole and its substituted derivatives were calculated using the hybrid B3LYP method with a lar...

The effect of a standing high-power high-frequency radio wave on the behavior of the F-layer ionospheric plasma is numerically investigated with the help of the mathematical model, developed earlier in the Polar Geophysical Institute. The mathematical model is based on a numerica...

Non-commutativity and uncertainty relation in quantum mechanics are considered here from the group-theoretic point of view. It is shown that uncertainty relation is connected with one of unit vector of orthogonal basis of spinor transformations space. The group-theoretic approach...
