Why we are using only KBr in IR spectrometer why not KCl
Answer Posted / ramkrishna thakare
KBr shows Absorbance in 2.4 -16 MICROMETER of IR REGION.
While other compound shows Transmittance in 2.4 -16
MICROMETER of IR REGION. & hence resolution is not achieved .
& for the purpose of resolution & background correction KBr
is the best option.
