Convert Coupling Constants into Splitting Ones.

Converting hyperfine coupling constants (HFCCs, \(A\) values in MHz) into hyperfine splitting ones (HFSCs, \(a\) values in mT).

Usage

convert_A_MHz_2a(A.MHz, g.val = 2.0023193)

Arguments

A.MHz

Numeric value/vector, corresponding to HFCCs in MHz.

g.val

Numeric value/vector, corresponding to actual \(g\)-factor (unitless). Default: g.val = 2.00231930 (corresponding to free electron).

Value

Numeric value/vector corresponding to HFSCs (\(a\)) in mT.

Details

Conversion performed according to the following relation: $$a = (A\,h\,10^{6})\,/\,(g\,\mu_{\text{B}}\,10^{-3})$$ where \(h\) corresponds to Planck's constant and \(\mu_{\text{B}}\) to Bohr's magneton. Both constants are obtained by the constans::syms$h and constants::syms$mub, respectively, using the constants package (see syms). The \(10^{6}\,/\,10^{-3}\) factor is introduced due to the specific \([A] = \text{MHz}\) \(\rightarrow\) \([a] = \text{mT}\) conversion. The latter is suitable for the EPR simulations and/or ENDOR.
