Abstract
Microwave and low resolution infrared spectra of some isotopically substituted molecules of ozone have been recorded. 1. Low temperature infrared spectra of $^{16}O_{3}$ and $^{18}O_{3}$ in gaseous state give the following zero order parameters expressed in $cm^{-1}$. $^{16}\omega_{1} = 1134.9 \quad \quad ^{18}\omega_{1} = 1070.0$ $^{16}\omega_{2} = 716.0 \quad \quad ^{18}\omega_{2} = 674.7_{5}$ $^{16}\omega_{3} = 1089.2 \quad \quad ^{18}\omega_{3} = 1026.5$ A Darling and Dennison resonance has been found. 2. 8 to 400 GHz microwave spectra of the five oxygen-18 substituted ozone molecules give the rotational constants in their ground state levels. 3. Both results lead to the anharmonic potential function of ozone.
