Coriolis Parameters in Local Mode States of Spherical Top Molecules

The coriolis interaction parameters of stretching vibrational overtones of spherical top molecules are discussed in the three widely used models.They agree with each other qualitatively on the calculation of coriolis interaction parameters of （n⁰⁰⁰） local mode states.For （2100） state,only calculation results of HCAOI model are close to experimental results,while NMDD and HCAO II models give rise to great discrepancies. Reason for discrepancy between HCAO I and II models has beend iscussed,the discrepancy results from their opposite eigenfunction forms.
