# How to measure absorbance at 882 nm?

I am trying to measure the absorbance of a solution at 882 nm, but this seems to be beyond the range of many UV-Vis spectrometers. Is this a job for the IR spectroscopy, or something else? I do not have much experience with IR spectroscopy.

Depending on the solvent deployed and the question addressed by the analysis, it is not this uncommon to characterize newly prepared materials by UV-Vis spectroscopy in a range of 200 or 250 nm to 1000 nm; because frequently you do not want to restrain your analysis in the determination of the maximal $\varepsilon$, but to record the absorption band completely. In addition, such an extended data set may be helpful to prepare / compare further characterisations, like ellipsometry, for example. If you are starting to record UV-Vis data on your own, I suggest consultation of a primer like this as a helpful reference.
