The authors have measured frequencies of N{sub 2}O transitions by heterodyning sub-Doppler fluorescence-stabilized N{sub 2}O laser radiation with that from a reference CO{sub 2} laser. A high-resolution cavity incorporates a ribbed tube and a highly reflective grating, permitting the CW oscillation of both the 10{degree}0-02{degree}0 9-{micro}m and the 10{degree}0-00{degree}1 10-{micro}m regular bands. This is the first sub-Doppler frequency measurement of the 9-{micro}m 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.
