calibration data using liquid DCM or ethanol

TDrake's picture

I have been building a novel device for NIR spectroscopy, and I am using several liquids as first tests of the device.  Unfortunately, I cannot find literature or database values of NIR transmission in the following liquids:
- ethanol
- dichloromethane/ methylene chloride
- soybean oil
I find this quite strange, as DCM, at least, is often used in NIR calibration.
I am looking in the 1000nm-2300nm region. I do not need very precise data, with the understanding that transimission spectroscopy depends quite a bit on the details of the setup.  I simply would like some data that I could include in and cite in a short paper.
Thank you!
