Natural isotopic abundance: 0.992728.

Reference

[99Mik2]

Method

Fourier transform spectroscopy.

Equations

Equations 6, 7, 19, and 20 in chapter “Introduction”.

Statistical errors

One standard deviation.

Remarks

All values are given in cm−1.

Molecular constants determined in the same fit are given in chapter “16O3 Vibrational Energy and Rotational and Centrifugal Distortion Constants for the Interacting Triad {(012), (210), (111)} and Dark (040) Vibrational States. Coupling Interaction Between the (111) and the Dark (040) States”.

The Darling-Dennison interaction between the (012) and (210) states is included in the fit with only one fixed parameter taken equal, as in chapter “16O3 Coriolis and Darling-Dennison Coupling Constants for the (002), (101), and (200) Vibrational States”, to −27.0 cm−1. Actually, no rotation corrections are needed since the mixing coefficients due to this interaction are small and practically constant.

A weak discrepancy for eight energy levels of the (111) state is found and assigned to a Coriolis interaction with the (040) state. The corresponding parameter C001 value is equal to 1.09 10−3 cm−1.

The isotopic composition of the elements used for the calculation of the natural isotopic abundance is taken from [2007Coh].
