WebThe value of the centro-symmetry parameter will be 0.0 for atoms not in the specified compute group. This parameter is computed using the following formula from (Kelchner) C S = ∑ i = 1 N / 2 R → i + R → i + N / 2 2. where the N nearest neighbors of each atom are identified and R → i and R → i + N / 2 are vectors from the central ... Web19 de ago. de 2024 · For example, compare PF 3, PCl 3, and PBr 3, with bond angles 97.8°, 100.3°, and 101.0°, respectively. In this series, the size of the pendant atom increases from F to Br while the central atom remains constant (phosphorous).
