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

“…Since the observed Zeeman splitting is smaller than the Doppler width of the molecular transitions (55 MHz) saturation spectroscopy is a convenient method to suppress the Doppler broadened linear absorption background [8]. In addition, the sensitivity of this method may be improved with the use of more sensitive methods for signal detection [7,8,9]. The two beams passing through the cell have crossed polarizations in order to avoid feedback into the laser.…”

“…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.…”
