During ir analysis why kbr background is required please tell me sir
The KBr Pellet Method exhibits the property that alkali halides become plastic when subjected to pressure and form a sheet that is transparent in the Infrared region.
The KBr does not show any absorption spectrum in IR region because it has a 100% transmission window in the range of wave number (4000-400 cm-1) at the FTIR spectroscopy with electronegativity of 2.0 based on the Pauling scale.
Therefore, Potassium bromide (KBr) is the commonest alkali halide used in the pellets during FTIR analysis.
Thank you sir
You are welcome…
