The seeded droplets then passed through an IR laser [an F-center laser (16)], where the solvated molecule was vibrationally excited. Relaxation of the excited molecule led to the evaporation of several hundred He atoms and caused a depletion of the droplet beam, which was detected with a bolometer (16). The IR spectrum was obtained by scanning the laser through the various vibrational bands and recording the laser-induced decrease in the He droplet beam intensity.
