This is a long shot, but maybe someone will know or can point me in the right direction. I'm looking for an experimental value for the contact angle between tetrahydrofuran (THF) with both mica and graphite substrates. I've done numerous googling and also did a search on the web of knowledge to no avail. I know the angle will be very small because THF wets both of those substrates quite well.

I suspect no measurements have been made however as THF evaporates in a matter of seconds at room temperature/pressure, but even so...

Thanks

You're into "splitting hairs" over the differences between "six" and "half a dozen" here. Adamson might help you.

Thanks, I will check out the book. Indeed you are correct about splitting hairs, I'm thinking that it might be best to just state that the angle is very small, but I would like to put a upper limit on it, I may have to make an estimate somehow. I will still have a look in Adamson just in case, thanks again!
