The 42Σ+→ X2Σ+ system in LiCa has been studied by Fourier Transform Spectroscopy. Here we present the analysis of the excited 42Σ+ state. Abundant dataset allowed us to construct accurate potential curve and to explain also the effective spin-rotation splitting of the rotational energy levels.
Another band system in LiCa was also studied, namely the 22Π-X2Σ+. This system has been already observed in absorption (L.M. Russonet al., J. Chem. Phys. 109, 6655 (1998)) but we were not able to detect any fluorescence when exciting at the reported transition frequencies. In this contribution we discuss the possible reasons.
