Experiment Details• Date: February 20, 2013

• Sample: 1,8-Dihydroxyanthroquinone (DHAQ)

• Solvent: Acetonitrile

• Laser / OPA: Coherent Libra @ 1 kHz / Harmonics Generator

• Pump power: 0.5 mW@400nm

• Gate wavelength: 800nm

• Measurement time: 40 min

• Detector: Thermoelectrically Cooled CCD

• SFG crystal angle was scanned at each time point in order to upconvert entire

fluorescence spectrum.

• Cosmic ray spikes automatically removed using Surface Xplorer.
