Hi everyone,
Is there any effect of the vacuum on the bandgap, for example between d-d orbitals ?
I am asking this since I have a blue copper complex that I put in 140 degC under very high vacuum and I noticed that the color changes from blue-green-yellow-transparent. Which either means that the bandgap is getting closer and closer, or the the Cu2+ was partially reduced to Cu1+.
Thanks and regards,
Yousef

More likely, you're simply drying a moist or hydrated solid. Does it seem likely to you that a macro effect, like vacuum, has an effect on quantum phenomena, such as d-d orbitals?
