Two-photon electronic absorption spectra of the tropyl radical (cyclic C7H7 ) have been observed by resonance enhanced multiphoton ionization spectroscopy (REMPI) from 415 to 590 nm, corresponding to 34 000–48 000 cm−1. Two Rydberg series are assigned and an ionization potential determined: np, δ=0.35; nf, δ=0.05; I.P.=50 177 cm−1. Vibrational activity of the Rydberg states was observed and the frequencies were found to be similar to the ion: ω2=862 cm−1 (ring breathing); 2ω18=1528 cm−1 (ring bending); and 2ω20=1284 cm−1 (CH out-of-plane bend).
