摘　　要：本文应用孙卫国等最近建立的代数方法(AM)和精确计算双原子分子离解能的新解析表达式研究了NaRb分子的X1∑+,(1)3∑+和a3∑+电子态的完全振动能谱和离解能.得到的完全振动能谱既重复了已知的实验能级,又给出了尚没有实验数据的高振动激发能级的正确数值,获得的各电子态离解能精确地符合实验值.这些结果为需要NaRb分子的精确振动能谱和离解能的科学研究提供了重要的数据.The full vibrational spectra and dissociation energies of the X^1∑^＋,（1）^3∑^＋ and a^3∑^＋ electronic states of NaRb molecule are studied using the algebraic method（AM） and the new analytical formula for dissociation energy proposed recently by Weiguo Sun and coworkers.The obtained full vibrational spectrum not only reproduce known experimental energies,but also give all high-lying vibrational energies which may be difficult to obtian experimentally.These results supply necessary data for the studies which need high-lying vibrational energies and dissociation energies of NaRb molecule.
