Abstract
We have measured frequencies of N2O transitions by heterodyning sub-Doppler fluorescence-stabilized N2O laser radiation with that from a reference CO2 laser. A high-resolution cavity incorporates a ribbed tube and a highly reflective grating, permitting the CW oscillation of both the 100 0-0200 9-μm and the 1000-0001 10-μm regular bands. This is the first sub-Doppler frequency measurement of the 9-μm band. The accuracy in the determination of the rotational constants for both bands has been improved by an order of magnitude, and calculated transition frequencies are presented
