The emission spectroscopy of the (2)Φ(5/2)-1(2)Δ(3/2) system of VO molecule

VO and other vanadium oxides are important in catalysts, semiconductors and optical devices. Studying its interior microstructure is necessary for fully understanding its intrinsic nature and better applications. The P and R-branch emission spectraof the (0, 0) band in the (2)Φ(5/2)-1(2)Δ(3/2) system of VO molecule are studied using the analytical formulae derived by Sun group in their previous work. The calculated result reproduced all known experimental spectral lines accurately, and the correct values of the unknown spectral lines up to J=80.5 were predicted in this work that were not given experimentally.
