摘要：

The microwave spectrum of a deuterated species of propylene, CH2DCHCH2, was investigated. Some of the 2 ← 1 transitions of the first-excited torsional state of the asymmetric form showed unusually large splittings and anomalous Stark effects. This observation was accounted for by an accidental degeneracy of the two J = 1 states, which were coupled by the tunnel effect and pushed away from each other. By analyzing the spectrum, the splitting due to the internal rotation was determined to be 19.3 and 768-795 Mc/sec for the ground and the first-excited states, respectively. © 1968.
