Abstract: In this study, two tunable pulse dye lasers have been used to probe the rovibrational levels of the 41Su+ and the nearby states by V-type optical-optical double resonance fluorescence depletion method through the intermediate B1Pu state levels. The processes are described as follows: B1Pu (v’, J’) ← X1S g + (v”, J”) + hυ1 41Su+ or nearby states ← X1S g + (v”, J”) + hυ2 In the energy region of 31600~36500 cm-1, we have observed some signals divided into six groups. To our analysis, the signals contain 164 rovibrational levels of 21Pu state , 268 rovibrational levels of 41Pu state, 159 rovibrational levels of 41Su+ state, 234 rovibrational levels of 51Pu state, and 65 rovibrational levels of 61Pu state. However the signals between 31800~32500 cm-1 can’t be determined evidently. According to the energy comparison of our results and some theoretical calculations, we still assign them to be 31Pu state preliminary. We oberved 46 rovibrational levels of the state. The Dunham coefficients and Rydberg- Klein-Rees (RKR) potential energy curves of the six states are determined by our temporarily vibrational numbering assignments.
