MICROWAVE SPECTRAL STUDY OF BICYCLO(2.2.2)OCTENE AND BICYCLO(2.2.2)OCTADIENE

Microwave spectral studies of bicyclo[2.2.2]octene (C8H12) and bicyclo[2.2.2]octadiene (C8H10) have led to the following rotational constants in MHz: for C8H12, A=2576.721±0.002, B=2508.998±0.002, C=2462.272±0.009; and for C8H10, A=2730.116±0.002, B=2650.520±0.002, C=2631.710±0.002. The dipole moments of the C2v molecules have also been obtained, the values along the symmetry axis being μc=0.253±0.001 D for C8H12 and μc=0.432±0.002 D for C8H10.
