Abstract
Spectral fluctuations of energy levels of an asymmetric-top rotor in strong electric fields are studied. Transition from a Wigner distribution for low excitation levels to a Poisson distribution for high excitation levels is found in an analysis of the nearest neighbour spacing distribution. Spectral rigidity Δ 3 undergoes an analogous type of transition. Consequences on the underlying classical motion are discussed.
