Question 15
CYMCQ1 markNeeds review
The character table for a pyramidal AB₃ molecule of C₃ᵥ point group is given below:
C₃ᵥ | E | 2C₃ | 3σᵥ |
A₁ | 1 | 1 | 1 | z | x² + y², z²
A₂ | 1 | 1 | −1 | Rz |
E | 2 | −1 | 0 | (x,y) (Rx,Ry) | (x²−y², xy) (xz, yz)
The reducible representation of pyramidal AB₃ is
C₃ᵥ | E | 2C₃ | 3σᵥ
Γ | 12 | 0 | 2
The CORRECT option representing all the normal Raman active modes of pyramidal AB₃ is:
