Infrared spectroscopy of OCS, SO2, O3 with a CO2 waveguide laser

Observation of the Zeeman Effect of Ozone by Doppler Free Laser Spectroscopy

“…According to Young et al [2] this ozone absorption is probably due to the transition (001) 119,2 - Further absorptions of 0 3 and other CO2 laser lines have not been observed, but it should be pointed out, that the assignments of several other lines found with a C0 2 waveguide laser [1,3] could also be verified, if necessary, by observation of the Zeeman effect. This work will be extended to the investigation of free radicals and molecular ions.…”

“…Absorptions of ozone have been reported with P(30) [3] and P(40) [2] of the 9.6 pm C0 2 laser band. A typical saturation signal at P(30) is shown in Fig.…”

“…In [3] and [11] an assignment of this absorption is given with (001) 16 8 9 -(000) 16 8 , 8 . Using the molecular constants of Barbe et al [4] and the components g aa , gt, b and g cc of the ^-factor given by Mack et al [5] we calculate the gj factors of both levels to be gj = -0.8209 yielding a splitting between o+ and cr_ transitions of 25.7 MHz at 20530 G. This is in good agreement with our observed splitting.…”

“…(i) There exist several coincidences between strong 0 3 absorption lines and several C0 2 laser lines [1,2,3].…”
