 +Ten rotational transitions with 3 ≤ //J// ≤ 5 and //K<sub>a</sub>// were identified with resolved methyl internal rotation splitting. A sufficiently large fraction of the lines is not or only marginally blended and above the 3//σ// noise level. The ketene to methylketene ratio is ~93; the ratio of methylketene to it isomer //trans//-propenal is about 2/3.\\
