The microwave spectrum of 2-bromopropene was reinvestigated with the use of microwave Fourier transform spectroscopy. For the two isotopic species CH3C79Br=CH2 and CH3C81Br=CH2 the bromine quadrupole coupling was determined with higher accuracy. The barrier hindering internal methyl rotation was obtained from the ground state.

The microwave ground state spectra of methylphosphine-borane-(11B) and methylphosphinetrideuteroborane-(11B) have been measured by microwave Fourier transform spectroscopy and analysed for 11B-nuclear quadrupole hyperfine splittings and CH3 and BH3 torsion fine structure. As high J transitions were measured a centrifugal distortion analysis was necessary. The B-P bond order is discussed.

The microwave spectrum of 2-chloropropene was reinvestigated using microwave Fourier transform spectroscopy. For the two isotopic species CH3C35Cl=CH2 and CH3C37Cl=CH2 the chlorine quadrupole coupling was determined with higher accuracy. The barrier to internal rotation was determined from the ground state. For comparison the first excited torsional state of CH3C35Cl=CH2 was remeasured and reanalysed
