Abstract
A method of analysing an aqueous fluid comprising obtaining a 2D-IR spectrum of a sample of the aqueous fluid using a 2D-IR spectrometer configured to apply a sequence of IR pulses to the sample, wherein the sequence comprises a pump process followed by a probe pulse, where the pump process is a single pump pulse or a sequence of a first pump pulse and a second pump pulse, and a waiting time Tw between applying the single pump pulse or the second pump pulse and applying the probe pulse is from 150 to 350 fs.
