How to calculate diamagnetic correction with equation
Accepted Answer
Diamagnetic correction is a factor used in magnetic susceptibility measurements to account for the contribution of the diamagnetic electrons in a molecule. The correction is typically calculated using the Pascal's constants, which are empirical values for different atoms and groups. Here is a general approach to calculate diamagnetic correction:
1. Identify the atoms and groups: Break down the molecule into its constituent atoms and functional groups.
2. Look up the Pascal's constants: Consult a table of Pascal's constants to find the values for each atom and group present.
3. Calculate the diamagnetic correction: Sum the Pascal's constants for all atoms and groups in the molecule. This will give you the diamagnetic correction for the entire molecule.
For example, the diamagnetic correction for methane (CH4) can be calculated as follows:
C: -6.00 x 10^-6 cm^3/mol
H: -2.93 x 10^-6 cm^3/mol
Diamagnetic correction for CH4 = (-6.00 x 10^-6 cm^3/mol) + 4
(-2.93 x 10^-6 cm^3/mol) = -17.72 x 10^-6 cm^3/mol.
Remember that this is a simplified approach. More accurate calculations might involve more specific Pascal's constants and adjustments for specific molecular configurations.
