A. Tokmakoff et al., VIBRATIONAL PHOTON-ECHOES IN A LIQUID AND GLASS - ROOM-TEMPERATURE TO10-K, The Journal of chemical physics, 101(2), 1994, pp. 1741-1744
Picosecond infrared vibrational photon echo experiments were performed
on the asymmetric CO stretching mode (1983 cm(-1)) of tungsten hexaca
rbonyl in 2-methylpentane from room temperature to 10 K using a free e
lectron laser. This is the first report of a room temperature infrared
vibrational photon echo in a liquid.
