Abstract
The beryllium monofluride (BeF) is astrophysically significant molecule.The radiative transition parameters such as Franck-Condon (FC) factor, r-centroids, electronic transition moment, Einstein coefficient, band oscillator strength, radiative life time and effective vibrational temperature have been computed for system of BeF molecule by the more reliable numerical integration procedure for the experimentally known vibrational levels using Rydberg-Klein-Rees (RKR) potential energy curves. The effective vibrational temperature of this system of BeF molecule was found to be nearly 5630 K. Hence, the radiative transition parameters as well as effective vibrational temperature help us to ascertain the presence of BeF molecule in the interstellar medium, S-stars and sunspots.
