Now, one thing you should know about coding single sigma bonds is that these bonds are able to rotate in space. They could rotate 360 degrees around. So since all these guides are sigma bonds, all of these bonds are able to rotate. And in fact, what confirmations are there are three dimensional structures related to one another by sigma bond rotations. For example, here I have one confirmation. If I rotate this bond some given amount of degrees, I will have a second type of confirmation.
