通过对角化有效哈密顿矩阵，研究了IBr分子在旋振基态的超精细结构和场效应。在研究J= 0能级的超精细子能级时，考虑了高J能级的微扰（最大到4），构造了一个80× 80的矩阵，并进行了求解。用道尔顿程序计算了一些实验上没有的分子常数。我们的结果将有助于冷IBr分子的操纵和进一步冷却的实验研究。
Hyperfine structures and the field effects of IBr molecule in its rovibronic ground state are theoretically studied by diagonalizing the effective Hamiltonian matrix. Perturbations of high-J levels up to 4 are taken into account when studying the hyperfine sub-levels of the J= 0 level, and thus, an 80× 80 matrix is constructed and solved. Some of the experimentally absent molecular constants are computed using Dalton program. Our results will be helpful in the experimental investigation of manipulation and further cooling of cold IBr molecules.
