Abstract
The effect of more than one pair of degenerate vibrational modes on the energy levels and spectrum of a doubly degenerate electronic state is discussed. The dynamic Jahn‐Teller effect for this case is treated by exact numerical methods and by approximation schemes. The effect of quadratic terms in the vibrational coordinates is also treated by these methods. The use of adiabatic surfaces in treating these problems is critically examined.Keywords
