Definition: The order of Cnv point group represents the total number of symmetry operations present in the Cnv group.
Purpose: It helps in understanding the symmetry properties of molecules in chemistry and physics.
The calculator uses the formula:
Where:
Explanation: The principal axis value is multiplied by 2 to account for both rotation and reflection symmetry operations.
Details: Calculating the order helps in molecular spectroscopy, predicting molecular properties, and understanding molecular symmetry.
Tips: Enter the principal axis value (n) which must be a positive integer. The calculator will compute the order of the Cnv point group.
Q1: What is Cnv symmetry?
A: Cnv refers to a point group that contains an n-fold rotation axis and n vertical mirror planes.
Q2: What's a typical value for n?
A: Common values are 2, 3, 4, etc., depending on the molecular symmetry.
Q3: Why is the order 2n?
A: Because Cnv groups contain n rotations and n reflections, totaling 2n operations.
Q4: What molecules have Cnv symmetry?
A: Examples include water (C2v), ammonia (C3v), and pyramidal MX3 molecules.
Q5: How does this relate to character tables?
A: The order determines the dimension of the character table and the number of symmetry species.
