dx^2-y^2 orbital

Postby DominicMalilay 1F » Wed Oct 21, 2020 11:23 am

Out of all the orbital structures in the d orbital, this one is the only structure that has the -y value in it. I was wondering about the reason for this.

I'm unsure if it's a negative sign or just a dash. In the lecture, when referring to the orbital, Lavelle just called it "x squared y squared".

I don't see any reason why the y should be negative in the orbital expression. I'm believe that it is just a dash connecting x^2 and y^2 to indicate them being a term together. dxy orbital locates in-between axis and dx^2-y^2 orbital locates along the x and y axis.

I think that its because the orbital is very similar looking to a hyperbolic functions

My mistake! I do find in other videos that people call it "x square minus y square" orbital, I think you are right about it has something to do with the hyperbolic function.
