So...a base stase can become another base state online due to external factor such as magnetic fiele, tunneling and so on?

That's very clear! Thank you! So orthogonality is a sort of "instantaneous" property?

But why Feynaman says that one should use orthogonal states? And then he doesen't use them for the ammonia?

But could the be used as basis states?

Hi guys! These days I've been reading Feynman's description of the quantum behaviour of an ammonia molecule. He assumes the N up or down as tuo basis states. He then says there's a little probability that the state UP becomes DOWN and viceversa. But for definition basis states are...
