Using the high resolution Fourier transform spectrometer the B2Σ+–X2Σ+ band system of AlO molecule has been recorded. The rotational structure of eighteen bands belonging to B2Σ+–X2Σ+ transition of AlO have been analyzed which led to accurate rotational and vibrational constants of ground and excited states. A few bands, viz. (2, 1), (3, 2), (4, 3), (2, 3), (3, 4), (4, 5), and (5, 6) were analyzed for the first time. Using these constants, the Franck–Condon factors and r-centroids were computed for the bands of B–X, C–X and C–A band systems for the v′ = 0–8; v″ = 0–8 matrix using the method developed by Jarmain and Nicholls. The F–C factors and r-centroids obey the established relationships. |
