¹⁶O¹⁸O¹⁶O Dipole Transition Moment Operator Constants, Integrated Intensities of the 2ν₂ + 5ν₃ and the 5ν₁ + ν₃ Bands

Abstract

This chapter provides the dipole transition moment operator constants, integrated intensities of the 2ν₂ + 5ν₃ and the 5ν₁ + ν₃ bands of ¹⁶O¹⁸O¹⁶O measured using continuous wave–cavity ring down spectroscopy.

Natural isotopic abundance: 0.00204.

Reference	[2013Sta]
Method	Continuous 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	The integrated intensities are given in units of cm/molecule at 296 K. Their values correspond to the sum of their individual line intensities, calculated with a cut-off equal to 1 × 10−28 cm/molecule at 296 K. Dipole transition moment operator constant is given in Debye. Calculated constants are purposely given with a supplementary digit, in index form, in order to reproduce the line intensities to experimental accuracy. Spectroscopic parameters are given in chapter “16O18O16O Vibrational Energy and Rotational and Centrifugal Distortion Constants of the (025), (501), and (dark4) Interacting States. Band Centers of the 2ν2 + 5ν3, and 5ν1 + ν3 Bands”. The isotopic composition of the elements used for the calculation of the natural isotopic abundance is taken from [2007Coh].
Abbreviations	SE: Statistical error.
	{A,B} = AB + BA
