Abstract
We present ^{12}CO(J=1-0 and 2-1) observations of a small sample of isolated early-type galaxies (ETGs). The data has been collected with the Arizona Radio Observatories (ARO) 12 m telescope at Kitt Peak. One object (KIG137) was unambiguously detected in both bands. For this detected galaxy we estimate of the molecular hydrogen mass. These observations are part of a larger project aimed at complementing existing data bases for the study of environmental effects on the interstellar medium in ETGs.
