Passhprase

I'm in a pretty dumb situation. I can acces my wallet, I have backed up everything except my Passhprase, or at least I just cannot find it. I wanted to make a transaction and it can't be done without the Passhprase. So in this case, can I do something? Is it possible to extract it from the wallet.dat, or using the wallet.dat in a freshly downloaded version of Raven Core? Or my Ravens have gone to the Moon without me?
