✦ Synopsis

The isotope effect on the vibronic spectrum of naphthalene has been investigated under conditions of h&h resolution, enabling the resolution of individual vibronic states Comparing the isotope effect for fixed vibronic states [cads to an U-Iexpected smoothing which is taken as evidence fdr a triplet communicating system, even though the singlet stare is chxrly not communicating.
