I Rotation operators on a sphere, around x and y axis

I need to start by saying that I'm not a physicist, nor a student of physics. I'm a translator, and my text is about rotations around the azimuthal nodal lines on the sphere.

I need to find a name for a particular type of a rotation operator, which rotates the sphere around the x and y axes.

Is there such a thing as a "nodal rotation operator"?

Hello Emily,

We're a careful bunch here ; could you post the paragraph(s) so we get some context ?

Oh, I've just learned the author of my text has invented the term :) I knew that! It's an operator that rotates nodal lines, hence "nodal rotation operator" seems appropriate. Thanks!
