The magnitudes of gluon and four-quark condensates are found from theanalysis of vector mesons consisting of light quarks (the families of $\rho$and $\omega$ mesons) in the 3 loops approximation. The QCD model with infinitenumber of vector mesons is used to describe the function $R(s)$. This modeldescribes well the experimental function $R(s)$. Polarization operatorscalculated with this model coincide with the Wilson operator expansion at large$Q^2$. The improved perturbative theory, such that the polarization operatorshave correct analytical properties, is used. The result is $<0 | (\alpha_s/\pi)G^2 | 0 > = 0.062 \pm 0.019 GeV^4$. The electronic widths of $\rho(1450)$ and$\omega(1420)$ are calculated.Comment: 18 pages, latex, changed content slightl
