Answer / mahi
because kbr is no any
peak in the rang of 400
to 4000.

Answer / amol pardeshi
KBr USED, WHICH SHOULD BE SPECIFICALLY OF SPECPURE GRADE ,
IS TRANSPARENT TO IR RADIATION AND DOES NOT HAVE ANY KNOWN
MODE OF VABRATION IN IR REGION OF 4000-400cm-1.
| Is This Answer Correct ? | 10 Yes | 1 No |
Answer / pramod s
Because KBr is IR absorbant so no any interferace in
sample in range between 4000 cm-1 to 400 cm-1 as well as
make a thin pellet.

Answer / selva
though both ans seems ok but what i feel is KBr shows no
