The observed spectrum of BO in the 1200-2100 cm(-1) region contains three bands: the fundamental bands of (BO)-B-11 and (BO)-B-10 and a hot band of (BO)-B-11 with band origins measured to be 1861.9242(97), 1915.3071(09) and 1838.3773(68) cm(-1), respectively. The resulting spectrum represents the molecular absorption and transmission, creating a molecular fingerprint of the sample. Some of the IR radiation is absorbed by the sample and some of it is passed through (transmitted). In IR spectroscopy, IR radiation is passed through a sample.

Water has a strong absorbance in the infrared 1113.The characteristic normal modes of the H 2 O molecule are due to vibrating OH bond whose frequencies are critically dependent on the aggregation state of water: gas, liquid and solid. FTIR stands for Fourier transform infrared, the preferred method of infrared (IR) spectroscopy. N2 - The Fourier-transform infrared emission spectra of BO were recorded using a Bruker IFS 125 HR spectrometer. T1 - Fourier-transform infrared emission spectroscopy of BO Fourier Transform Infrared Spectroscopy (FTIR) is an effective analytical technique for quickly identifying the chemical family of a substance. Fourier transform infrared spectroscopy is a versatile method for detecting lubricant contaminants, additives, and lubricant degradation byproducts.
