Abstract

The fluctuations in the intensities of rotational bands in the S ₁ manifold of benzene are analyzed in detail. The extent of mixing is found to increase with energy and those bands which could not be assigned are found to have an intensity distribution characteristic of the chaotic limit. At a given energy, those bands which borrow intensity due to resonance coupling are more mixed and the C₆D₆ bands are more strongly coupled than those of C₆H₆.
