The column density ratios of the //l//-H<sub>2</sub>C<sub>//n//</sub> molecules with //n// = 3 to 6 is about 344 : 561 : 1 : 4.4; reflecting the decrease with //n// on one hand and the lower column densities for //n// being odd on the other hand.\\ | The molecule was identified through 11 unblended to somewhat blended //a//-type transitions with 6 ≤ //J// ≤ 10 and //K<sub>a</sub>// = 0 and 1 in the course of a molecular line survey of the prototypical cold dark molecular cloud TMC-1 carried out with the Yebes 40 m radio telescope between 32.8 and 49.2 GHz.
