Can we crowd source the refractive index for Methamphetamine freebase. The data should be listed as nD 20 followed by 1.?

What is the refractive index of Methamphetamine freebase?
If you are going to respond with quantitative data to a request for it include a reference to where you found the data and make it a trust worthy source like a scientific journal article. I expect the data to be represented as nD 20 or 25(for measurement taken at 20 degrees celcius or 25 degrees C) followed by some value between 1.3 - 1.7 .

By crowdsource, I assume you man will someone else look it up for you? Maybe someone will, if they are incredably bored, but I doubt it. The reason is because you might find a reference that highly defined, but you'll never repeat it. It's the composite of several different measurements using several different devices, and even if you used identical devices, there's going to be a bit of varience, let's say 2%. That 2% times 3 measurememnts is a 6% varience, so the point is moot

This is close enough to suit me. Who knows the fact that I responded might motivate someone to waste that 20 minutes iof thier life just in the name of one-upmanship.

2-Methyl-1-phenyl-1-propanone is not Methamphetamine free base. The word Methamphetamine refers to the molecule 1-Phenyl-2-Methylaminopropane.
