Franck–Condon factors factors and r-centroids have been calculated for the G3Φ4-X3Φ4 , K3Φ4-X3Φ4, L3Φ4-X3Φ4, [20.6]3Γ5-X3Φ4 and [34.7]3Γ5-X3Φ4 bands of Cobalt monofluoride 59Co19F from the best available molecular constants using Morse and Rydberg–Klein–Rees (RKR) methods. The reliability of the obtained values was verified by comparing the results of five different programs. Based on the calculated Franck–Condon factors values, the appearance of the bands in these systems are discussed and the relationship between the r-centroids and the band-origin wavenumbers and wavelengths are also determined along with accuracy factors.
