# Abstract:

The process of calculations on the theoretical determination of the electric quadrupole strength is systematized to a certain extent. The requisite formulas of the mathematics of tensor operators are given for configurations with one and two unfilled shells. It is shown how to apply the multiconfiguration approximation to the theoretical determination of the probability of a quadrupole transition. The effect of the multiconfiguration approximation on the results of calculations for atomic species of carbon, nitrogen, and oxygen type is examined. The radial integral appearing in the expression for the probability of a quadrupole transition is evaluated both with analytic orbitals and with solutions to the Fock self-consistent-field equations for a number of atomic species of the aforementioned types.
