Observations of the Zeeman effect in the 3 mm lines of CN have been carried out with the 30 m IRAM telescope toward seven dense molecular clouds. Detections were achieved toward the Orion Molecular Cloud 1 (OMC1), toward two cores in the DR21OH molecular cloud, and probably toward the M17SW molecular cloud. The line-of-sight magnetic field strengths inferred are Blos(OMC1) = -0.36 ± 0.08, Blos(DR21OH1) = -0.36 ± 0.10, Blos(DR21OH2) = -0.71 ± 0.12, and Blos(M17SW) = -0.33 ± 0.14 mG. The theoretical implications of these results are discussed.
