Thanks in advance. Cheers!

I want to rotate one molecule as regard the same molecule in another position, that is, the rotation should keep the Eckart conditions. As you know the Eckart conditions involve the same center of masses for the two molecules and the conservation of the angular momentum. The conservation of the angular momentum does that there is only one valid combination of the Euler angles. My problem is find this combination of Euler angles. Anybody knows how to do that?
