Using the dynamicalsymmetry and considering the off-diagonal term of rovibrational interaction, weobtained firstly the expression of rotational energy levels similarly to thecommonly used term value equation in spectrum analysis. By using the formula,the rotational levels of different vibrational transition for linear triatomic molecules〓, HCN, OCS,〓 and its isotope species, which are on the electronic groundstate and the first electronic excited state, were analyzed. The obtained rotationalconstants accord with the ones from other calculation methods very well.
