  • Exercise 3

      Similar and related symmetry operations are collected together into classes. The symmetry elements and operations of the NH3 molecule are listed below.  
    Elements: E, C3, σ, σ, σ Operations: E, C3, C32, σ, σ, σ
    Collected into classes these operations may be written: E, 2C3, 3σ

    Group the symmetry operations of BF3 into classes ( E, C3, C32, S3, S35, C2, C2, C2, σh, σv, σv, σv)
