Hi, iam James Haskins, Have a splendid day!
Why Is Nacl And Kbr Used In Ir Spectroscopy? [Solved]
Wow, that’s a lot of info! Basically, NaCl is a cheaper option than KBr for infrared sampling. It has a similar refractive index to KBr, so it lets IR light pass through well. But it has a higher cutoff wavelength than KBr, so depending on how thick the crystal is, it might limit the range of wavelengths you can measure.
