Abstract
The free jet millimeter wave spectrum of 1,3-dioxepane has been invest igated in the 60-78 GHz frequency range. Rotational transitions belong ing to the ground vibrational state have been observed and measured, y ielding the rotational constants A = 3565.780(2), B = 3193.448(1) and C = 1936.312(2) MHz. The absence of low lying vibrational satellites a nd the kind of transitions observed (only mu(a)-type) demonstrate that , in contrast with previous reports, the molecule is rather rigid and possesses C-2 symmetry.
