Abstract

The microwave spectrum of the equatorial isomer of propylene ozonide has been assigned. The rotational constants (in MHz) for the normal isotopic species are A = 7574.36, B = 3476.33, and C = 2644.79: Dipole moment components (in D) are $\mu_{a}$ = 0.74, $\mu_{b}$ = 1.06, and $\mu_{c}$ = 0.10, with $\mu_{T}$ = 1.29. The molecular structure has been determined using the rotational constants from several isotopically substituted species. The ozonide ring has the O-O half-chain conformation. Transitions arising from two excited vibrational states have been assigned.
