摘要
The complete line list of rovibrational transitions of the X (1)Sigma(+) state of LiH is computed. The line list includes all possible dipole-allowed transition energies and oscillator strengths that cover the transition energy range 3.27-19476 cm(-1). The line list was obtained using an accurate potential and dipole moment function constructed from available experimental and theoretical data. This paper discusses the agreement of the current calculations with previous theoretical and experimental results. We also provide the radiative cooling function in the high-density limit over a wide temperature range and compare them with previous results. A simulated collisionally-broadened LiH opacity relevant to cool dwarf stars is also presented.
