The tensor mesons f, A2 and A3 are analysed within the frangework of QCD sum rules. We account for the effects of gluon and quark condensates phenomenologically, via the matrix elements 〈0|g2|0〉 and 〈0|Ψψ|0〉. The G2 term in the sum rules is found with the help of a new computational technique developed recently. Our results for the masses of f, A2, A3 and their coupling constants agree with experiment.
