Beginning of ReadMe : J/A+A/398/L11 Vinylacetylene millimeter-wave spectrum (Thorwirth+, 2003) ================================================================================ The millimeter-wave spectrum and the dipole moment of vinylacetylene. Thorwirth S., Lichau H. <Astron. Astrophys. 398, L11 (2003)> =2003A&A...398L..11T ================================================================================ ADC_Keywords: Atomic physics Keywords: molecular data - methods: laboratory - techniques: spectroscopic - stars: AGB and post-AGB Abstract: 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 mua and mub have been performed leading to the result mua 0.4D. The value for the dipole moment component mub is very low and lies in the range of several thousandth to a few hundredth of a Debye.
