This chapter provides the resonance coupling parameters of the dark (601), the (305) and the dark (252) interacting states of 18O3 measured using continuous wave–cavity ring down spectroscopy.

Natural isotopic abundance: 8.62 × 10−9.




Continous Wave – Cavity Ring Down Spectroscopy.


Equations  19 and  25 in chapter “ Introduction”.

Statistical errors

One standard deviation in units of the least significant full size digit.


All values are given in cm−1.

Statistical errors are given in parentheses.

Calculated parameters are purposely given with one supplementary digit, in index form, in order to reproduce the energy levels to experimental accuracy.

Molecular constants determined in the same fit are given in chapter “ 18O3 Vibrational Energy and Rotational and Centrifugal Distortion Constants of the Dark (601), the (305) and Dark (252) Interacting States.”

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