Abstract

The energetics and the energy-resolved decay of the S₁(¹B_2u) electronically excited state of the pentacene molecule in seeded supersonic beams has been investigated. Two low-frequency, intense spectral features located at excess vibrational energies of 77 cm^-1 and 202 cm^-1 above the origin were observed, and provide spectroscopic evidence for the quasiplanarity of the isolated pentacene molecule in its first-excited singlet state.
