The pure rotational spectrum of the hydrocarbon vinylacetylene in its ground vibrational state has been investigated from 80 to 165 GHz, covering the rotational quantum numbers 8<=J=<18 and 0<=Ka<=17, n order to provide accurate rest frequencies for radioastronomical searches. Moreover, quantum chemical calculations of the dipole moment components {mu}a and {mu}b have been performed leading to the result {mu}a~0.4D. The value for the dipole moment component {mu}b is very low and lies in the range of several thousandth to a few hundredth of a Debye.
