The extraction of spectroscopic constants from rovibrational spectra provides valuable insights into the molecular structure and behavior of diatomic molecules. In this study, we focus on the lithium molecules in the first excited state. Using a pulsed laser, we measure the rovibrational transitions of lithium molecules in the A state, allowing us to extract key spectroscopic constants such as the fundamental vibrational frequency, bond strength, anharmonicity constant, the depth of the potential well, and so forth. Through the analysis of these constants, we gain a deeper understanding of the molecular potentials. The results are compared to theoretical predictions and values obtained for other alkali dimers, providing valuable benchmarking for molecular models. This work lays the groundwork for future studies in high-resolution molecular spectroscopy, quantum chemistry, and applications in quantum information science and molecular simulations.
