Paper Abstract

This study is the continuation of our analysis of emission spectra of pure D20. The spectra have been recorded in the 320 - 860 and 1750 - 4300 cm-1 spectral regions at different pressures and temperatures. The measurements were performed in an alumina cell with an effective length of hot gas of about 50 cm. All spectra have been recorded by using the Bruker IFS 120 spectrometer at the Physikalisch-Chemisches-Institut, Justus-Liebig-Universitat Giessen (Germany). More than 5600 lines have been assigned to the second triad {(030), (110), (011)} of interacting states of the D2160 molecule. These transitions were assigned to 24 vibration-rotation and rotational bands. An extended set of more than 1500 experimental rovibrational levels for the (030), (110), and (011) interacting states has been obtained. The maximum values of rotational quantum numbers are Jmax = 30 and Ka max = 21 with Emax = 10568 cm-1 for the (011) state; Jmax = 29 and Ka max = 21 with Emax= 10540 cm-1 for the (030) state, and Jm 26 and Ka max 22 with Eniax 10488 cm1 for the (110) state. A comparison of the observed energy levels with the best available values from literature and with the global prediction is discussed.
