I'm learning to deal with h2+ (hydrogen ion) problems and the like, which sure entails the infamous born oppenheimer approximation .(adsbygoogle = window.adsbygoogle || []).push({});

i know the word "adiabatic" in a thermal sense, that is , an adiabatic process is the one in which no heat transfer occurs between the things of question and surroundings.

but , I don't quite understand that in quantum mechanics ,how the notion of "adiabatic" enters the story, say, in particular born oppenheimer approximation and adiabatic approximation is synonym .

it's said that the notion of adiabatic has a lots of applications in many branches of physics, would anyone please but tell me some of them?

many thanks in advance :D
