Doppler-free polarization spectroscopy of the B 1Π u state of Cs 2
Abstract
With Doppler-free polarization and OODR spectroscopy, about 1000 rotational transitions in different vibrational bands of the Cs 2(B 1Π u←X 1Σ g+) system have been measured to an accuracy of 10 -3 cm -1. From the measured term values, Dunham coefficients, RKR and IPA potentials of the B 1Π u state have been calculated which yield the potential parameters Te=13043.73 cm -1, Re=0.485 nm, De=2338 cm -1.
