Isotope Bands and the Vibration Assignment of theD2pgr;gmdash;A2pgr;uSystem of N2+

摘要

TheD2pgr;gmdash;A2pgr;ubands of (N215)+have been studied in the 2050 to 2570hyphen;Aring; region in order to determine the correct vibrational quantum number assignment. The results obtained from the study of the isotope shifts of the band heads show that the quantum number of the previously observed lowest vibration level of theDstate isv=3. The potential energy curve of theDstate has also been calculated by means of the Rydbergmdash;Kleinmdash;Rees method, which has been modified by Vandersliceet al.
