摘要：

A U(3) <----> O(4) transitional description of diatomic molecules in the U(4) vibron model is considered. The analysis includes the U(3) and O(4) limits of the theory. Applications to vibrational-like band-heads of several diatomic molecules indicate that there are significant deviations from the O(4) limit of the theory. (C) 2003 Elsevier B.V.
