✦ Synopsis

The lowest excited singlet site of 9,10-dihydroanthracene has been studied by supersonic-jet laser spectroscopy. The spectrum consists of a number of prominent low-frequency vibronic bands near the O-O band followed by a structureless continuum. The low-frequency vibronic bands are nicely fitted with a quadratic Gaussian-type potential for the excited state. The height of the barrier of the double-minimum potential is found to be 94 cm-'
