The rotational spectrum of allyl bromide was recorded from 8.7 to 26.5 GHz at -20 ◦C with a waveguide chirped-pulse Fourier transform microwave spectrometer. The rotational spectrum of allyl bromide has been previously studied by Niide and coworkers. a,b However, previous assignments of this spectrum only extended to J = 12 and Ka = 1. Newly acquired data from our spectrometer has allowed us to extend the previous work to higher values of J and Ka, leading to significant improvements in the distortion constants in particular. Comparisons between the spectra and conformational preferences of the allyl halides will also be discussed.
