    How to draw the symettry axis for 1-fold rotation ? And why C1v is identical to C1h ?
    Thanks

    Think about what a 1-fold rotation means!

    Oh ! I think 1-fold rotation means no symmetry so there is no axis of semmetry. Is that correct ?

    Why the point group C1h is identical to C1v ?
    Why the point group C1h with horizontal twofold axis is identical to C2v ?
    Thanks
