Abstract

The rotational structure of sixteen vibration rotation bands of the 15N218O molecule in the 2−5μ region has been measured and analyzed. Since the molecule 15N218O is the heaviest of all the stable isotopic species of nitrous oxide, the study of its infrared bands allowed the determination of very accurate values for the equilibrium internuclear distances rN−N=1.12665±0.0005\AA and rN−O=1.18565±0.0005 {\AA}$. The distance between the end atoms is determined with a much higher precision (rN−N+rN−O)=2.31230±0.00003\AA.
