In IR spectroscopy for the preparation of pellet we use KBR
Because kBR has no absorbance in IR region

Answer / b srinivasu
Kbr and sodium chloride cells are alkyl halides so its donot react and do not exhibit any absorbance spectrum

Answer / mahesh
in IR kbr shows 100% trasmisson.so we prepare pallet with sample than it shows only spectrum of sample.also kbr is inactive in IR.

Answer / ajeet pratap singh
KBr is IR inactive in nature so it use in pellet preparation.
KCl also can be use.
