Analysis of the Highhyphen;Resolution Zeeman Spectra of Nitrogen Dioxide in the Near Infrared

摘要

Highhyphen;resolution (sim;0.03 cmminus;1) longitudinal Zeeman spectra in absorption and magnetic rotation spectra have been obtained for the (1, 0, 1) and (2, 0, 1) vibrationndash;rotation bands of14NO2and15NO2. Equations are derived which predict the Zeeman splittings of the molecular energy levels (neglecting nuclear spin) as a function of field and the rotational transition probabilities for the longitudinal Zeeman spectra. Computerhyphen;generated plots of the predicted Zeeman spectra show quantitative agreement with the experimental spectra at all available magnetic fields (up to 6800 G). The dependence of the observed magnetichyphen;rotation spectra on the magnetic field strength can be understood qualitatively from the predicted Zeeman patterns.
