Analysis of High-Resolution Spectra of 18O3

“…A: 0.3-0.7 cm In various tables (1,4,5,7,8) only cases B, C, and D are reported. The best case, A, appeared only for studies available for 16 O 3 (15).…”

“…In addition to the principal Coriolis v 1 3 , v 3 ± 1 Coriolis type due to the proximity ω 1 + ω 3 ∼ = 3ω 2 , previously observed below 3300 cm −1 , we have observed the following localized resonances (2): * Coriolis type:…”

High-Resolution IR Spectra of 18O-Enriched Ozone: Band Centers of 16O16O18O, 16O18O18O, 18O16O18O, and 16O18O16O

“…Recently reported analysis of 14 bands of 18 O 3 (3,4) at high resolution has confirmed the validity of the potential function of Ref. (2) for complete isotopic substitution.…”

“…As in the previous studies of 16 O 3 (1) and 18 O 3 (3,4), the rotational analysis has been performed using effective Hamiltonians for strongly interacting vibrational states where the diagonal blocks have the standard Watson's form and the off-diagonal blocks account for Coriolis and Darling-Dennison resonances arising from the similarity of the 1 and 3 harmonic frequencies (1, 2). Because of the lower symmetry of the C s isotopic species, the off-diagonal blocks of the Hamiltonian matrices contain both Coriolis-and anharmonictype terms (8).…”

“…(3,4), a new code for assignments, based on ground state combination differences, has been used which has allowed us to assign the strongest in P and R lines for K ϭ 0, 1, and 2. The well-known procedure of new fits and assignments leads to the final assignment of most of the observable transitions and accounts for the various resonances.…”
