With IRsolution, the threshold value, the noise level, and the minimum area are required as parameters for peak detection.

WebWhat is FTIR? FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample. http://www.cheminfo.org/flavor/c6h6/cheminformatics/IR_spectra_prediction/index.html
