We want to use the A1Σ+-X1Σ+ transition of KH to assign the rotational quantum numbers (J) of the B1П electronic excited state. However, the fluorescence of the B1П-X1Σ+ is weak, and there is interference with the existence of other fluorescence. Therefore, we didn’t confirm by the experiment. However, we can calculate and analyze the B1П electronic excited state of KH with the term value of the X1Σ+ ground state. Finally, we do the preliminary observation of the C1Σ+ electronic excited state by optical-optical double resonance.
