Natural isotopic abundance: 4.19 × 10−6.
Reference | [2014Sta] |
Method | Continous Wave – Cavity Ring Down Spectroscopy. |
Equations | Equations 47 and 52 in chapter “Introduction”. |
Statistical errors | One standard deviation in units of the least significant full size digit. |
Remarks | Dipole moment constant values is given in Debye. The calculated constant is purposely given with a supplementary digit, in index form, in order to reproduce the line intensities to experimental accuracy. The integrated intensity is given in units of cm/molecule at 296 K. Its value corresponds to the sum of its individual line intensities, calculated with a cut-off equal to 1 × 10−28 cm/molecule at 296 K. Spectroscopic parameters are given in chapter “18O16O18O Vibrational Energy and Rotational and Centrifugal Distortion Constants of the (143) and Dark (520) Interacting States. Band Center of the ν1 + 4ν2 + 3ν3 Transition”. The isotopic composition of the elements used for the calculation of the natural isotopic abundance is taken from [2007Coh]. |
