The D 1 Π state of the NaRb molecule
نویسنده
چکیده
We present a detailed experimental study of the DΠ state of the NaRb molecule by means of Fourier transform spectroscopy of laser induced fluorescence. The entire data field for the DΠ state of NaRb and NaRb consists of rovibrational levels with v′ = 0−39 and J ′ = 1−200. The data were incorporated into a direct fit of a single potential energy curve to the level energies using the Inverted Perturbation Approach method. The DΠ state q factors, which describe the Λ-doubling, have been obtained in a wide range of rotational and vibrational quantum numbers. Analysis revealed several perturbation regions in the DΠ state.

متن کاملTautomeric equilibria for ionized oxamic acid - inhibitor of LDH
Amide-iminol tautomerism was studied for ionized oxamic acid (OA+•) in the gas phase using theDFT method with the UB3LYP functional and various basis sets {6-31++G(d,p), 6-311+G(d,p), and augcc-pVDZ}. Among twenty tautomers-rotamers possible for OA+•, eleven isomers were found to bethermodynamically stable. Similarly as for the neutral molecule, ionization (OA → OA+• + e) favors theamidization ...
