What is the refractive index of Methanol in the Infra Red range?

Click For Summary
SUMMARY

The refractive index of pure Methanol (CH3OH) in the Infrared range is approximately 1.3288, as noted in the CRC Handbook of Chemistry and Physics. However, this value lacks specific frequency details, which are crucial for accurate applications. The discussion highlights the importance of considering frequency dependence due to Methanol's distinct infrared "fingerprints." For comprehensive data, users are directed to the RIODB database, although it currently only provides transmission spectra up to 2.5 microns.

PREREQUISITES
  • Understanding of refractive index concepts
  • Familiarity with infrared spectroscopy
  • Knowledge of chemical properties of Methanol
  • Experience with data interpretation from scientific databases
NEXT STEPS
  • Research the frequency dependence of refractive indices in organic solvents
  • Explore infrared spectroscopy techniques for analyzing Methanol
  • Investigate the RIODB database for additional spectral data
  • Learn about the implications of concentration on refractive index measurements
USEFUL FOR

Chemists, materials scientists, and researchers in optical engineering who require precise refractive index data for Methanol in infrared applications.

I'm looking for Methanol (CH3OH)
refractive index (n,k) table in Infra Red 2-10micron
If anyone can help me with that
 
Engineering news on Phys.org
What kind of concentration are we talking about? If it's small, you can use the index of water as a good approximation.
 
I think the OP needs data for "pure" methanol.
 
In my CRC handbook of chemistry and physics, it has a value of 1.3288. But it doesn't tell me at what frequency this value is for.
 
Thanks, for your help.
But Methanol has a "finger prints" at IR range
that means that frequency dependence can't be ignored.
(at least for my needs)
 
I checked this data base already but all they have it's transmission spectra up to 2.5 micron
