Borel-transformed QCD sum rules are applied to pseudoscalar mesons containing a light antiquark and a light or heavy quark. We determine the decay constants and the SU(2) mass splittings of these mesons. A suitable method of extracting the hadronic parameters from the sum rules is discussed in detail. The relationship of these sum rules to the current algebra sum rules is p emphasized. Our results are in good agreement with the experimental results, where available.
