Scientific paper

Using a specific scheme of the QCD sum rules, one derives the relation for
leptonic constants of $nS$-wave heavy qiarkonia, so $f^2_{n_1}/f^2_{n_2}=
n_2/n_1$, that does not depend on the quarkonium content, and it is in a good
agreement with the experimental values of constants for the $\psi$- and
$\Upsilon$-families.
