Photoionization-induced large-amplitude pendular motion in phenol(+)-Kr

Miyazaki, Mitsuhiko; Takeda, Akihiro; Ishiuchi, Shun-ichi; Sakai, Makoto; Dopfer, Otto; Fujii, Masaaki

The dynamics of the intermolecular motion of the phenol+–Kr cation generated by photoionization of the neutral π-structure is probed by picosecond time-resolved infrared spectroscopy. The spectrum at zero delay displays only the free OH stretch band of the π-structure. The appearance of the hydrogen-bonded OH stretch band of the H-structure after a few ps is due to ionization-induced π → H site switching. Spectra at long delay (>20 ns) show that the Kr atom delocalizes from one π-site of the aromatic ring to the opposite π-site via the OH-site, like a pendular motion in the classical picture.
