The paper presents calculation of radiative parameters (Einstein coefficients of spontaneous radiation, oscillator strengths for absorption, Franck-Condon factors, wave numbers of rotational lines in the system of bands B1Π−X1Σ+ of KRb molecule (0 ≤ ν’ ≤ 12, 0 ≤ ν’’ ≤ 30, j’ = 0,20,41, 50, 70,100)) and radiative lifetime of the excited electronic state. The calculations are performed on the basis of semi empirical potential energy curves built in the current paper. Both vibrational energies and wave functions are found as a result of a numerical solution of the radial wave equation.
