Rotational spectra of tert-butyl bromide and iodide measured in the millimetre-wave region and by Fourier-transform techniques
Abstract
Millimetre-wave rotational spectra have been recorded for the molecules (CH3)3C79Br, (CH3)3C81Br and (CH3)3C127l. In addition, we have recorded low-J spectra at much greater precision using a Fourier-transform spectrometer. The combined results yield rotational, centrifugal distortion, quadrupole and spin–rotation constants which are more accurate than any determined independently.
