Overlap with nearby broadened line

In summary, there is a real benefit in measuring the spectra of VOCs with uiue-solvable rotational fine structure by measuring the spectrum at lower resolution than 2cm . When Av is much greater than 8cm , however, the bands are broadened to the point that they can overlap neighboring bands from other analytes, and the prediction errors increase. For small molecules with resolvable rotational fine struc-mre, the effect of resolution on analytical accuracy depends on the presence of other analytes with nearby absorption bands and the presence of water lines in the same spectral region.
