Abstract
The pure rotational spectrum of 3-vinylbenzaldehyde (3VBA) has been measured and assigned. Coker College's chirped-pulse Fourier transform microwave (CP-FTMW) spectrometer was used to measure the rotational spectrum of 3VBA in the 7.5 - 18.5 GHz region of the microwave spectrum. The results have been analyzed to discover the rotational constants and centrifugal distortion constants of four distinct conformations of 3VBA: \emph{cis,cis}-, \emph{cis,trans}-, \emph{trans,cis}-, and \emph{trans,trans}-3VBA. The experimental rotational constants have been compared to the results of \emph{ab initio} calculations. The performance of Coker's CP-FTMW spectrometer will also be discussed.
