Calculations of Einstein spontaneous emission coefficients for vib-rotational transitions in HCl laser

United with RKR potential function and the newest EDMF, the program Level developed by Prof. Le Roy of Canada to calculate bi-molecule spectroscopic constants was used to compute the Einstein spontaneous emission coefficients(A coefficients) for fundamental band transitions with vibrational energy level of V<6. The database of HCl's A coefficients was retrieved, and it seemed that Level is a rather simple but robust tool for quantum electronics researchers.
