Adjacent to the conventional mid-IR (MIR) region (4000-400 cm-1) the near-IR (NIR) region of the spectrum covers the interval from about 10000-4000 cm-1 (1000-2500 nm). Due to the limited qual. aspects this wavelength range has so far been primarily applied for quant. anal. of OH-, NH- and CH- functionalities. Recently, however, it has been recalled to the attention of spectroscopists by the introduction of fiber-optic probes for process-control and remote sensing in combination with chemometric data handling procedures for multicomponent anal. and identity control.
