New observations of weak overtone transitions of N2O by ICLAS-VeCSEL near 1.07 μm ☆

Abstract We have completed our investigations of the weak overtone transitions of nitrous oxide near 1.05 μm by the study of the 9090–9560 cm−1 region by intracavity laser absorption spectroscopy (ICLAS) using a vertical external cavity surface emitting laser (VeCSEL). Eight bands were rotationally analyzed. Two hot bands are newly observed while the rotational analysis of the six cold bands has been improved. This Note includes the correction of a few misprints in the rovibrational parameters and the reconsideration of the analysis of an interpolyad Coriolis interaction system given in our previous contribution [J. Mol. Spectrosc. 220 (2003) 80].
