摘要：

The polarised two-photon excitation spectrum of crystalline dibenzofuran at 4.2 K has been measured. Only totally-symmetric vibrations are active, and their relative intensities are similar to those in the one-photon spectrum already reported. No factor-group splittings are found. The origin in the two-photon spectrum has a width of ≤ 10 cm-1 in contrast to a width of ≥ 250 cm-1 in the one-photon spectrum, now attributed to extreme inhomogeneous broadening. © 1979.
