New frequencies are given for the [sup 12]C[sup 16]O[sub 2], [sup 13]C[sup 16]O[sub 2], [sup 12]C[sup 18]O[sub 2], and [sup 13]C[sup 18]O[sub 2] regular band laser transitions and for the hot-band transitions of [sup 12]C[sup 16]O[sub 2]. These frequencies are based on a new least-squares analysis of all the frequency measurements of these four molecular species including new high-J measurements reported here and recent absolute frequency measurements. Fourteen new high-J transitions of the regular [sup 12]C[sup 16]O[sub 2] laser bands have been observed, the lasers have been stabilized with sub-Doppler saturated 4.3-[mu]m fluorescence, and their frequencies have been measured. Nine of these transitions fill the gap between the 9.4- and 10.4-[mu]m bands. Saturated 4.3-[mu]m fluorescence also has been used to stabilize the 01[sup 1]1-[11[sup 1]0,03[sup 1]0][sub 1] and 01[sup 1]1-[11[sup 1]0,03[sup 1]0][sub 2] hot-band laser lines. New frequency measurements are reported for 84 hot-band lines, which were also included in the reanalysis of the CO[sub 2] laser transitions.
